Use Virtual Work Method to answer the questions below considering the truss shown. Use the cross-sectional areas (A, in2) specified in the figure, E = 30 ksi and a = 20 x 10°/ °F. "a" is hinge supported and "c" is roller supported. 4. Solve for the horizontal displacement of joint d in inches due to external force only. Put (-) negative sign if its to the left. 5. Solve for the horizontal displacement of joint d in inches due to -100 °F change in temperature in members ad and cd. Don't add deflection due to external loads or fabrication error. Put (-) negative sign if its to the left.
