Question: Consider the staircase truss shown in the accompanying figure. There are 14 steps, each with a rise of 8 in and a run of 12 in. The members have a cross-sectional area of 4 in2 and are made of steel with a modulus of elasticity of E = 29 x 106 lb/in2. Using ANSYS, determine the deflection of each joint, the stress in each member and the reaction forces. Verify your results
