1. (a) Compute all reactions and draw the shear and moment curves for the beam in Figure P10.11. Given: EI is constant. Compute the deflection at the midspan of segment BC.

2. (a) Determine the member end moments for the rectangular ring in Figure P10.12, and draw the shear and moment curves for members AB and AD. The cross section of the rectangular ring is 12 in. × 8 in. and E = 3000 kips/in.2. (b) What is the axial force in member AD and in member AB?
