Problem 2: 1. Identify Reaction Forces at mounts (fixed get 2, rolling get 1) 2. Draw a free body diagram of node with fewest unknowns 3. Draw and label unknown forces 4. Sum forces in X and Y 5. Use similar triangles to calculate x from y or y from x 6. Draw newly found forces on truss diagram 7. Reflect truss forces to opposite ends 8. Repeat with remaining nodes Name Period Date: A 100 N 1 m 1 m B
