Shear and moment diagrams with bevel gears

Click For Summary
SUMMARY

This discussion focuses on analyzing shear and moment diagrams for bevel gears, specifically addressing the forces and moments acting at the connection between the bevel gear and the shaft. The key components to identify include the moments (Mx, My, Mz) and forces (Fx, Fy, Fz) at the interface. Participants emphasize the importance of selecting an appropriate origin point and establishing a clear coordinate system (x, y, z axes) to facilitate accurate calculations. Sketching orthogonal or perspective views is recommended to visualize the problem effectively.

I have attached the problem. I am a bit confused on how this schematic works.

The 3 forces on the bevel gear should translate to 3 moments where the bevel gear connects to the shaft. Will there also be any forces where it connects to the shaft?

Choose an origin, say where bevel gear meets shaft. Identify x y and z axes. If necessary sketch 3 orthogonal views of the situation, or, better, a perspective sketch. Then, where the bevel gear meets the shaft, identify the Mx, My, Mz, Fx, Fy, Fz components of the actions. The rest should follow if you can do that.
