Hints and Discussion Thread
Equilibrium
- Draw individual FBDs of gears C, D and H.
- Assume positive torques in all members.
- You may want to review the positive sign conventions for torques in Chapter 8 of the lecture book.
- Write down the equilibrium equations for C, D and H. Is this problem determinate?
- Solve for the torques in the three shaft components.
Angles of rotation
Use the torque/rotation equations and compatibility to determine the rotations of C, D and H.
