(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.
