Revie Consider the steel truss shown in Figure 1) to answer Parts A, B, and C below, where P1 = 32 kN and P2 = 58 kN The cross-sectional area of each member is A = 200 mm. and E = 200 GP. Part A - Horizontal displacement Use the method of virtual work to determine the horizontal displacement of joint D due to the applied loads. Let a positive answer representa displacement to the right and a negative answer represent a displacement to the left. Express your answer in the appropriate units to three significant figures.

Part C - Change in temperature Determine the vertical displacement of joint E if, in addition to the applied loads, members BE and CE experience a temperature increase of AT = 21 °C. The steel's coefficient of thermal expansion used in the truss is 1.20(10 5)/K. The truss is still subjected to external loads P, and P2. Let a positive answer represent an upward displacement and a negative answer represent a downward displacement. Express your answer in the appropriate units to three significant figures. ► View Available Hint(s) MA ? ΔΕ. = Value Units Submit
