Question
The pin-jointed truss in Figure Q1 below is pinned supported at A and roller supported at C. (CO2:PO2)(C3) 20 kN/m E D 4 m 4 m 3 m 6 m 6 m 3 m Figure Q1 a) Determine the vertical displacement at B using the Virtual Work Method if in addition to the loads shown, member BE is cooled down by 30°C. Given the thermal expansion coefficient, a= 1x10-5/PC and the axial rigidity, AE = 20,000 kN. (CO2:PO2)(C4)
