Use a computer program to assist in the design problems in Problems

A pulpwood loader as shown in Figure P5–63 is to be designed to lift 2.5 kip. Select a steel and determine a suitable tubular cross section for the main upright member BF that has attachments for the hydraulic cylinder actuators AE and DG. Select a steel and determine a suitable box section for the horizontal load arm AC. The horizontal load arm may have two different cross sections AB and BC to reduce weight. The finite element model should use beam elements for all members except the hydraulic cylinders, which should be truss elements. The pinned joint at B between the upright and the horizontal beam is best modeled with end release of the end node of the top element on the upright member. The allowable bending stress is in members AB and BC. Member BF should be checked for buckling. The allowable deflection at C should be less than 1=360 of the length of BC. As a bonus, the client would like you to select the size of the hydraulic cylinders AE and DG.
