1. As shown in the figure, a steel bearing plate must transfer an axial load of 20 kip to a concrete pad. The compressive stress in the concrete must not exceed 400 lb/in². Assume that the load is equally distributed across the plate, and that the plate is thick enough so that it does not bend. a. Find the minimum required area of the plate so that the concrete stress is not exceeded. b. If the bearing plate is to be square, what will be the minimum plate size to the next nearest "? 20 KIP Concrete pad Steel plate 2. A 34" diameter low carbon steel rod measuring 10' in length is to be used to support a 10 kip load hung from one end of the rod. Neglecting the weight of the rod: a. determine the stress in the rod. b. determine the elongation that will result. 3. A 2" x 2" x 30" aluminum bar is subject to a compressive load of 40 kip. For this bar determine: a. the compressive stress. b. the lateral deformation. c. whether the cross-sectional area of the bar will increase or decrease.
