Water Boiling at Room Temperatures, Under a Vacuum
 
02:44
If the water pressure goes up, as in the bottom of the Mariana Trench; where the pressure is about 7.5 tons per square inch, then the boiling and freezing points of the water goes up, If, however, the atmospheric pressure goes down, as on the top of Mount Everest, then the boiling and freezing points of the water goes down. In the case of the top of Mount Everest, the boiling point of pure water is about 72 C. The experiment shows how water can boil at quite low temperatures, under a vacuum.

A Video On The Finite Element Method.
 
11:46
The finite element method is one of the most powerful numerical methods available for solving partial differential equations; which apply over complex shapes. Very often, in engineering science, it is difficult to solve a partial differential equation, which applies over a complicated shape. The process therefore is to sub-divide the complex shape into lots of simpler shapes, on which the complex differential equation can be solved. The process then is to solve the complex differential over each simpler shape and 'join' all the simpler shapes together, ensuring compatibility and equilibrium at the inter-element boundaries. This often results in thousands of simultaneous equations, which can be solved on a digital computer. Writing of the computer program is 'relatively simple', compared with solving such a difficult mathematical problem by traditional methods. The method can be used for structural analysis, dynamics, vibrations, fluid flow, thermodynamics, acoustics, electrostatics, magnetostatics, seepage through porous media, electrical and fluid networks, electronics, etc., etc. Large commercial computer packages are available, such as PAFEC, ANSYS, NASTRAN, ABACUS, LUSAS, etc., etc; which make solution relatively simple for most problems in engineering.

"Proof" of Einstein's Theories of Relativity.
 
08:23
The video shows an experimental 'proof' of Einstein's Theories of Relativity, by the experimenter carrying a £40,000 atomic clock; while taking a return trip by jet plane from England to New Zealand. Einstein's Theories of Relativity were called the Special Theory of Relativity; which was dependent on the speed you travelled at; the faster you travelled at, the less you would age. The General Theory of Relativity was dependent on your position from (say) the Earth and the acceleration due to gravity. The purpose of the journey was to prove both theories. Einstein presented the Special Theory of Relativity to the World in 1905 & the General Theory of Relativity in 1916. He won the Nobel Prize for Physics in 1921; the proceeds of which he handed over to his 'divorced' wife "Mileva".

Tensile Test Experiment
 
02:38
The Load-Extension relationship in the linear region is not easy to read; this is because the holes at the end of the specimen; through which the tensile load is transmitted, suffer from some initial settlement and also, elongate somewhat; due to stress concentrations. To calculate the Young's modulus, I recommend that you use an extension of about 0.065mm; which corresponds to a tensile load of about 2000N. This is a standard "Strength of Materials" test carrried out by most engineering students. The students should consult: [1] Bird, John & Ross, Carl (2002) "Mechanical Engineering Principles", Newnes, Oxford, UK. [2] Ross, C.T.F. (1999) "Mechanics of Solids", Horwood, Chichester, UK.

Thin-Walled Circular Cylinders Under Internal Pressure
 
05:00
Pressure (bar) Vs Micro-Strain Readings: Press=0; Long=5.4; Hoop=4.2: Press=10; Long=26.5; Hoop=144: Press=20; Long=53.7; Hoop=203: Press=30; Long=79.8; Hoop=412. Thin-Walled Circular Cylinders under Uniform Internal Pressure, appear in a number of different forms, including aircraft and spacecraft fuselages, aerosol cans, beverage cans, boilers, condensers, gas containers, etc. The theory discussed in this video should not be used for designing thin-walled circular cylinders under uniform external pressure, because the latter vessels can implode at a fraction of the pressure to cause the same vessels to burst under uniform internal pressure.

Collapse Of Submarine Pressure Hulls_2nd Edition-20-02-2011.
 
34:38
At the bottom of the Mariana Trench, the hydrostatic pressure is a little under 8 ton per sq.in (1200 bar, approx.). Now a double-decker London bus weighs about 8 tons; thus a large submarine, diving to the bottom of the Mariana Trench, will effectively have the equivalent of the weight of a double-decker London bus on each square inch of its pressure hull. Thus, for a submarine pressure of diameter 10 m (32.8 ft) & length 80 m (262.5 ft.), will carry a load equivalent to about 4 million London buses on its pressure hull; if it dives to the bottom of the Mariana Trench! It is for thsi reason, that the submarine pressure hull is one of the most difficult structures to design. The 'voice over' video shows the collapse modes of a submarine pressure hull, together with a video of a submarine conquering the Mariana's Trench. This video shows that there is life at the bottom of Challenger Deep, which is situated deep in the Mariana's Trench.

The Video shows some of the effects of German bombing on the London infrastructure. Until a few years ago, photographs from the World War II were only seen in grainy black and white. The brunt of the attacks on London by the German bombers was between September 7, 1940 and May 10th 1941. The attacks on Britain were carried out continuously for 76 nights and killed over 40,000 people. These terrifying attacks did not break the spirit of the Brits and people pressed on with their lives, as you can see in the photos. If you have followed the history of World War II, you will recall that on July 19th 1941 Sir Winston Churchill launched his "V for Victory" campaign. On the 70th anniversary of this campaign, with the advent of digital and other technologies, new color images of the horror of destruction inflicted by the Nazi bombings of London have emerged.

Submarine 'Turtle', built by Bushnell in 1776
 
00:46
The manually operated submarine, the 'Turtle', was built by the American Bushnell in 1776, during America's War of Independence from British rule. To operate the vessel, one needed Herculean strength, together with enormous dexterity. The vessel was built from wood and partly covered with copper sheets. It had manually operated propulsion for both vertical and horizontal motion. It also had a metal screw on its top, which was intended to penetrate the wooden hulls of British warships, so that an explosive could be attached to the enemy ship hulls. It is not known whether or not the 'Turtle' sunk any of Britain's warships during that period?

Weather and Climate Changes_Milankovitch Cycles.
 
06:16
The video demonstrates the 3 Milankovitch Cycles, due to Astronomical Changes. These cycles are due to: 1)Eccentricity of the Earth's Orbit around the Sun. 2) Obliquity of the Earth's Axis of Rotation 3) Precession of the Earth. or due to it wobbling about its axis of rotation. The author concludes that the present bad weather is not due to the Milankovitch Cycles, but due to a redistribution of the Earth's mass caused by the melting of the Arctic and the Antarctic due to the Greenhouse Effect. The author states that the wobbling of the Earth due to the Greenhouse Effect is not dangerous, but will cause us some bad weather.

Global Warming & Fossil Fuel Burning

At the bottom of the Mariana Trench, the hydrostatic pressure is a little under 8 ton per sq.in (1200 bar, approx.). Now a double-decker London bus weighs about 8 tons; thus a large submarine, diving to the bottom of the Mariana Trench, will effectively have the equivalent of the weight of a double-decker London bus on each square inch of its pressure hull. Thus, for a submarine pressure of diameter 10 m (32.8 ft) & length 80 m (262.5 ft.), will carry a load equivalent to about 4 million London buses on its pressure hull; if it dives to the bottom of the Mariana Trench! It is for thsi reason, that the submarine pressure hull is one of the most difficult structures to design. The video shows how we can deal with the concomitant problems of global warming and fuel shortages. The video shows that there 10,000 billion of methane hydrates buried under the deep water ocean bottoms and describes methods of how we can retrieve this methane; whose value is 536 times the GDP of the USA. The video also shows that if we burn this methane the atmospheric CO2 will increase by 1511%. The video shows that we can bury this CO2 in the deep oceans; where it will turn into CO2 hydrates at depths of water as little as 250m. The author concludes that, "We can have our cake and eat it too".

Engineers' "Nobel" Prize
 
02:26
Astronomers and Cosmologists are not Rocket Scientists; they are Space Scientists, and most Rocket Scientists are Chartered Engineers or their equivalents. Let me also add, that the engineering courses in the western world for chartered engineers and their equivalents, for which I have experience of, for over 50 years, including at Russell Group universities & at ex-Polytechnic universities, etc., at both undergraduate and postgraduate levels; do not, in general, stifle the imagination of the engineer; whereas this may not be true of some of the equivalent courses in some of the other parts of the world. Thus, do not worry  too much, about the number of engineers that are being produced by the  universities of some of the other parts of the World! The imagination of Chartered Engineers or their equivalents, helped humankind to set foot on the Moon, and remember what  Einstein said about imagination; he said, "Imagination is more important than knowledge, because knowledge is limited, but imagination encircles the world". Moreover, the Chartered Engineers and their equivalents, who helped put humankind on our Moon, did not get a Nobel Prize for this feat, because they do not have Nobel Prizes in Engineering! In case any artisan engineers read my blog, and they are fearful of their job prospects, and they have not got enough money to enroll for a full-time degree in chartered engineering, I suggest to them that they may consider enrolling for a foundation degree in engineering; while still working for a living. They can enroll for a part-time foundation degree in engineering at their local college or their local ex-Polytechnic University for a relatively small fee. For many of these courses, they need only attend the educational establishment for about 1/2 a day per week; during term time, for a few years. After they have got their foundation degree, they can then enroll for a one year full-time engineering degree; which may lead them to becoming a Chartered Engineer and hopefully, a more secure career! In my opinion the combined qualifications of an artisan engineer, together with the qualifications of that of a Chartered Engineer, are a "Winner"; Planet Earth needs this combination badly!

Buckling of Axially Loaded Struts in Compression
 
05:13
If a slender member of a structure is subjected to axial compression, it can buckle at a fraction of the load that would cause the same member to fail under axial tension. Thus, structural engineers should be very careful when dealing with a slender member which is in compression; even though the compressive stress may be small. Such a structure can collapse catastrophically with disastrous consequences.

VIBRATION of a Submarine Pressure Hull Using ANSYS

The video shows how to use ANSYS 11, to determine the resonant frequencies of a submarine type pressure hull. The program uses an 8 node quadrilateral element called Shell 93. If ANSYS 13 is being used, then this element is not available and an element called Shell 281 should be used instead. However, if Shell 281 is used, its thickness has to be fed in by clicking "Section"; then "Shell"; then "Add Layer"', & not using "Real Constant"; otherwise, the 2 elements are similar.

Bottle Buckling_Simulating Submarine Presure Hull Collapse
 
01:00
DANGER! Only responsible & careful adults, wearing suitable & protective clothing should attempt to repeat this experiment. The video shows a corrugated plastic bottle filled with steam and it is then sealed. When the steam cools the vessel is subjected to an internal vacuum and buckles. This is similar to a submarine pressure hull imploding under the action of uniform external hydrostatic pressure in a buckling mode. The external collapse pressure causing the vessel to implode and buckle is usually only of a fractional value of the internal pressure to cause the same vessel to rupture or explode.

Buckling of a Rail Car Tank Under External Pressure
 
01:30
This video shows the folly of an inadequate design and/or incorrect operating procedures. Apparently the rail car tank had been 'steamed out' and it was very hot inside; when it rained heavily; this caused it to rapidly cool inside and form an internal vacuum; equivalent to uniform external pressure. The tank had a vent designed to release the surplus internal pressure; but not to 'release' an internal vacuum! Also, as the design of the tank was to operate at an internal pressure, it had no vacuum support rings on it (i.e. It was not ring-stiffened or corrugated; like a typical vessel under external hydrostatic pressure). The collapse occurred very quickly, as we have found with our experiments at the University of Portsmouth; see my home website on: http://homepage.ntlworld.com/carl.ross/page3.htm

They paid my expenses, but did not give me a fee for my efforts and they forced me to keep the project secret; I did keep the project secret, until now.. Moreover, I was not expecting a fee. When the programme was transmitted, the "BBC" decided to edit me out. Moreover, they decided not to acknowledge me, and I thought that this was very cruel of them & unprofessional; because had I not carried out the design of the van, they would not have been able to produce that scene.
