- Homework Statement
- Draw a FBD, determine the largest torque, T1, and find shear stresses in CD and DE
- Relevant Equations
- Method of sections, static equilibrium
I wish to draw a proper free-body diagram for this shaft. However, my FBD does not agree with the solutions manual. If someone could point out where I erred, that would be great.
This is what I drew:
From my FBD, it is clear that the maximum torque is present in section DE of the shaft.
We can use the equation shear stress=Tc/J in conjunction with the maximum allowed shear stress of 60 MPa as follows:
Then, to find the maximum shear stresses in sections CD and DE:
