1) Draw a Global Free Body Diagram (FBD)

2) Make a cut in the global FBD and draw the cut FBD

3) Write out the equations of motion required to solve

4) Solve the global equations of motion (units are important, PLEASE include them, it will help teach you how to make sure you solving the EOM correctly if you balance your units as you solve)

A bar is loaded with torques To as shown in the figure. The beam is rigidly attached to a solid wall on the left at A, while the right end at E is free. The left and right sections of the beam each have total length L, and diameter D, while the middle section of the beam has length L and diameter 2D. Both cross-sections are solid and circular. The entire beam is made from the same material, having a shear modulus, G. Rigid Wall To 43 2D L B D To E
