고체역학 (Beer) — Stress and Strain—Axial Loading: Problem 2.76

2.76 What load P should be applied to the plate of Prob. 2.75 to produce a 1/16-in. deflection? (Context from Prob. 2.75: The plastic block shown is bonded to a rigid support and to a vertical plate to which a 55-kip load P is applied. Knowing that for the plastic used G = 150 ksi, determine the deflection of the plate. Dimensions from Fig. P2.75: height = 4.8 in., width = 3.2 in., thickness = 2 in.)
