Using Virtual Work Method

For the truss shown:

a) compute the vertical components of the displacement of joint C. In addition to the load , the temperature of member BD is subject to a temperature increase of 60°F. For all bars, E = 29,000 kips/in.², A = 4 in.², and α = 6.5 × 10⁻⁶ (in./in.)/°F

b) If bars AB and BD are fabricated 3/4 in . too long, compute the vertical displacement of "joint C" . Neglect all the applied loads.

For the truss shown:
a) compute the vertical components of the displacement of joint C. In addition to the load, the temperature of member BD is
subject to a temperature increase of 60°F. For all bars, E = 29,000 kips/in.?, A = 4 in.?, and a = 6.5 x 10-6 (in./in.)/°F
b) If bars AB and BD are fabricated 3/4 in . too long, compute the vertical displacement of joint C. Neglect all the applied loads.
