1. Determine the impact factor.
11. | Determine the maximum shortening of the spring due to the impact
14 a) A circular rod of length L and cross section area A is attached to spring having 5

stiffness K as shown in the figure.

Let 8 is the young’s modulus and © be the coefficient of thermal expansion of the
rod. If the bar subjected to temperature increase of AT, determine the expression
for thermal stress developed on the cross section.
b) What is endurance limit? Explain the failure mechanism of components under 5

fatigue loading.
