Question: 1. When the 20-kip load is applied to joint B of the truss in Figure P8.9, support A settles vertically downward 3/4 in. and displaces 1//2 in. horizontally to the right. Determine the vertical displacement of joint B due to all effects. The area of all bars = 2 in.2, and E = 30,000 kips/in.2.

2. (a) Compute the horizontal displacement of joint B produced by the 240-kN load in Figure P8.10. For all bars, area = 2400 mm2 and E = 200 GPa.

(b) Assuming that no load acts, determine the horizontal displacement of joint B if support A moves 20 mm to the right and 30 mm down and support E moves downward 36 mm.
