How do i calculate shear stress on a Key and a bolt?

Click For Summary
SUMMARY

The discussion centers on calculating shear stress on a key and a bolt in the context of Solidworks Simulation certification. The user references a specific formula for shaft torque, defined as 8 times the force acting on a bolt multiplied by the radial distance to the shaft axis. Shear stress calculations are suggested to follow a method outlined in a previous discussion, emphasizing the importance of showing workings for clarity. The thread concludes with a directive to post calculations in the homework forum for further assistance.

PREREQUISITES
  • Understanding of shear stress concepts
  • Familiarity with Solidworks Simulation tools
  • Knowledge of torque calculations
  • Basic proficiency in engineering mechanics
NEXT STEPS
  • Review the method for calculating shear stress as discussed in the linked Physics Forums thread
  • Practice torque calculations using the formula: Torque = 8 x Force x Radial Distance
  • Explore Solidworks Simulation certification requirements and common pitfalls
  • Engage in the homework forum to post and discuss shear stress calculations
USEFUL FOR

Engineering students, Solidworks users preparing for certification, and professionals needing to calculate shear stress in mechanical designs.

I have been attempting the Solidworks Simulation certification but keep just missing out by a few marks and I believe these questions are the main ones which are killing me.

I haven't done these calculations in years and I've been lost with how to do the hand calc's. Any help would be appreciated.
