2. Use the method of virtual work. Determine the vertical displacement of joint A (a) if members AB and BC experience a temperature increase of AT = 200°F. Take A = 2 in^2 and E = 29(10^3) ksi. Also, a = 6.60 (10^-6)/°F. (b) if member AE is fabricated 0.5 in. too short. Include the effect of external forces in both cases. 8 ft B 8 ft 500 lb 1000 lb 8 ft
