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  in. If σ = 40 ksi and Est = 29( 103) ksi, what is the strain in each boll when the nut is unscrewed so that the clamping force is released?
