A straight rod of solid polymer is of length 1 m and diameter 10 mm. The polymer is linearly viscoelastic with a tensile creep compliance given by:

D = 2- exp(-0.1t); Gpa^-1

Where t is in hours. The rod is suspended vertically and a mass of 10 kg is hung from it for 10 hours. a) Find the change of length of the rod. b) Identify the time domain of this property test procedure.

A massless rod of length L = 2.3 m stands up straight, fixed to the ground by a bolt. A horizontal force of 8.2 N is applied at a vertical distance of L/2 to the right. To counter this force and keep the rod stationary, a wire is fixed at the top of the rod and attached to the ground some distance away to the left, making an angle of 45 degrees to the horizontal. a) What is the tension...
