Question: 1. For the steel rigid frame in Figure P8.31, compute the rotation of joint B and the horizontal displacement of support C. Given: E = 200 GPa, A = 500 mm2, I = 200 × 106 mm4.
2. (a) Compute the slope at A and the horizontal displacement of joint B in Figure P8.32. EI is constant for all members. Consider only bending deformations. Given: I = 100 in.4 , E = 29,000 kips/in.2.
(b) If the horizontal displacement at joint B is not to exceed 3/ 8 in., what is the minimum required value of I?
