Consider the steel truss shown in (Figure 1) to answer Parts A, B, and C below, where P₁ = 38 kN and P₂ = 60 kN. The cross-sectional area of each member is A = 400 mm², and E= 100 GPa . ▼ 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 represent a 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 B - Vertical displacement Use the method of virtual work to determine the vertical displacement of joint E due to the applied loads. 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.

Determine the vertical displacement of joint E if, in addition to the applied loads, members BE and CE experience a temperature increase of AT= 20 °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 P₁ 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.
