Question

3-D FBD worksheet (related to Section 5.1 & 5.2) Draw a complete Free-Body Diagram for the following problems, 1. Draw the FBD of the rod. The rod end at A has rollers along its vertical direction. 2. Draw the FBD of the beam. 900 N/m 3. Draw a FBD for determining the reactions at A and the tension in the cable (cylindrical weight is 80 lb). 4. Draw the FBD of the 40 kg uniform rod AB.
