A100mm long steel bush with 39.98mm internal diameter and 60mm outer diameter is force fitted onto a steel tube. the150mm long steel tube has 40.02mm outer diameter and 25mm internal diameter. the steel tube is subject to an internal pressure of 20mpa. what is the resulting interference pressure between the bush and the tube, assuming that their nominal diameters are 40mm? the young's modulus for steel should be taken as 200gpa and the poisson's ratio as 0.28

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
