...is given as K and not °K). A difference of 1 K is the same as a difference of 1 °C but the Kelvin scale starts from a different zero point. 0 °C corresponds to the temperature at which water freezes (at the Earth’s atmospheric pressure). 0 K, which is equal to −273.15 °C, corresponds to absolute zero where all motion of atoms stops, so 10,000 K is 9726.85 °C! The Celsius ......

...c) large vehicles present access and drivability problems. Obviously, the driver has to be able to access and fit into the vehicle Figure 1. This can be a problem for very large or very small people. In fact, even people who are only a little taller than average may struggle in the case of some sports cars (see Figure 2) where vehicle height might be restricted by styling...

...C in euros per cubic metre for some materials. (a) Derive a merit index that increases as the total cost K of supporting compressive load L with a strut of height h decreases. Hint: You will need to introduce the cross-section area A into the total cost and the maximum load – you can then eliminate it from a combination of the two expressions. (b) Calculate the index...
