Question: The members of the roof truss shown in the accompanying figure have a cross-sectional area of approximately 21.5 in2 and are made of Douglas-fir wood with a modulus of elasticity of E = 1.9 x 106 lb/in2. Using ANSYS, determine the deflection of each joint, the stresses in each member, and the reaction forces. Verify your results Also, replace one of the fixed boundary conditions with rollers and obtain the stresses in each member. Discuss the difference in results
