Consider a plate with a variable cross section supporting a load of 1500 lb, as shown in the accompanying figure. Using direct formulation, determine the deflection of the bar at loca tions y = 2.5 in, y = 7.5 in. and y 10 in. The plate is made of a material with a modulus of elasticity E 10.6 x 10' ksi. 10 in. 4 in. 1500 lb thickness=0.125 in. 25 in. 5 in.
