Engineering Mechanics problem with solution.

3–40. The head H is connected to the cylinder of a compressor using six steel bolts. If the clamping force in each bolt is 800 lb, determine the normal strain in the bolts.Each bolt has a diameter of 3/16 in. If sY = 40 ksi and Est = 291103/2 ksi, what is the strain in each bolt when the nut is unscrewed so that the clamping force is released?
3–41. The stress–strain diagram for polyethylene, which is used to sheath coaxial cables, is determined from testing a specimen that has a gauge length of 10 in. If a load P on the specimen develops a strain of
P = 0.024 in/in., determine
the approximate length of the specimen, measured between the gauge points, when the load is removed. Assume the specimen recovers elastically.
