For the Maxwell viscoelastic model: a) Derive the differential equation for this model and use the differential equation to write the expressions for the case of stress relaxation and creep. b) Draw the predicted time vs. strain response for the case of creep, and the predicted time vs. stress response for the case of stress relaxation. c) Discuss whether the Maxwell model would be capable of accurately describing the creep and stress relaxation behaviors of a polymer.

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
