Question: 1. If the horizontal displacement of joint B of the frame in Figure P8.40 is not to exceed 0.36 in., what is the required I of the members? Bar CD has an area of 4 in.2, and E = 29,000 kips/in.2. Consider only the bending deformations of members AB and BC and the axial deformation of CD.
2. For the steel frame in Figure P8.41, compute the horizontal displacement of joint B. For member BCD, A = 6000 mm2 and I = 600 × 106 mm4. For member AB, A = 3000 mm2. E = 200 GPa for all members.
