Question: 1. For the truss in Figure P8.3, compute the horizontal and vertical components of the displacement of joint C. The area of all bars = 2500 mm2, and E = 200 GPa.
2. For the truss in Figure P8.4, compute
(a) the vertical displacement of joint C,
(b) the horizontal displacement of joint C, and
(c) the horizontal displacement of joint D. Members AB, BC, and CD have area = 1 in.2, and members AE, ED, BE, and CE have area = 0.25 in.2, and E = 10,000 ksi.
