Question: 1. (a) Compute the reactions in Figure P9.42. For all members, E = 4000 ksi and I = 1000 in.4. Spring CD has a stiffness of 5 kips/in.
(b) Compute the vertical deflection of joint B. (c) Recompute the reaction at C if joint A settles by 0.5 in.
2. Determine all reactions and draw the shear and moment diagrams for beam BC in Figure P9.43. Assume member AB has 2EI while BC has EI.
