Consider a laminated pressure vessel composed of two thin coaxial cylinders as shown in figure. In the state prior to assembly there is a slight "interference" between these cylinders, i.e., the inner one is too large to slide into the outer one. The outer cylinder is heated, placed on the inner, and allowed to cool, thus providing a "shrink fit." If both the cylinders are of steel and the mean diameter of the assembly is 100 mm, find the tangential stresses in each shell arising from the shrinking if the initial interference (of diameters) is 0.25 mm. The thickness of the inner shell is 2.5 mm, and that of the outer shell 2 mm. Take E = 200 GPa. 100 mm Laminated pressure vassel Outer cylinder Inner cylinder

Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. Such a radiator, made of copper, is filled to its 12-L capacity when at 10.0°C. -What volume of radiator fluid, in liters, will overflow when the radiator and fluid reach their 99.5°C operating temperature, given that the fluid’s thermal coefficient of volume expansion is 400.0 × 10-6 / °C? The coefficient of volume expansion for copper is 5.1 × 10-5 /°C.

It is important for the body to be able to cool itself even duringmoderate exercise. Suppose a 70kg man runs on a treadmill for 30min and at a (total)metabolic energy expenditure rate of 1000W. Suppose also that the man cannot perspire; and cannot lose any heat viaconduction, convection and radiation (as would be the case with astronauts wearing theirair-tight spacesuit but w/o portable cooling unit). By how much would the man’s bodytemperature increase at the end of the 30min exercise? Express your answer in oC. A) 0.5B) 1.4C) 3.1D) 5.7E) 8.8
A gasoline engine is at a location where the temperature is measured to be 14.2 °C and produces 347 KW at 5800 rpm while consuming 0.0184 kg's of fuel. During operation, data shows that its mechanical energy loss is 18 %, the actual volume of air going into each cylinder is 80% (the volumetric efficiency has a negligible variation), and the actual fuel-to-air ratio is 0.065.
