**Determining Support Reactions** **Text:** Determine the support reactions at A and C for the following. The support at A is a thrust bearing. The reactions must be shown on a free body diagram for full credit. **Diagram Description:** - The diagram shows a bent rod supported at two points: A and C. - Point A has a thrust bearing, which allows rotation but provides thrust forces. - The rod is bent with a 9 ft length from A to D and a 3 ft segment from D to B. A lateral extension of 2 ft is depicted from B to C. - A force of \( F = 120 \, \text{lbs} \) is applied downward at point B in the negative z-direction. - The diagram is labeled with three axes: x, y, and z, indicating the three-dimensional layout. **Support Reactions Table:** - \( A_x = A_y = 0 \, \text{lbs} \) - \( A_z = 481 \, \text{lbs} \) - \( T = 72 \, \text{lbs} \) - \( M_{ax} = 432 \, \text{ft-lb} \) - \( M_{az} = 0 \, \text{ft-lbs} \) This setup and calculated reactions provide a clear understanding of how external forces and moments are resisted by the supports at A and C, ensuring equilibrium of the system.
