1. Determine the reactions at supports A and B for the beam shown below. Solve for the internal forces at the mid-point of the beam. Take a free-body cut at the mid point and use both FBDs to solve the internal forces - show that both FBDs give you the same answer . 500 1b 800 lb 700 1b 400 lb -30- 30-4 30- - 3 01- -30 2. Determine the reactions forces at support A. Solve for the internal forces at Im from the wall and I'm from the free end of the beam. 2 kN 3 kN.m B 2 m 2 m
