Question

This problem I am struggling to get started because I need to 1- find the point of interest to then 2- find the state of stresses and 3- then find principal stresses, for finally then finding 4- Tresca and Von Mises safety factors.

The main thing for me here is that I am not sure how to go on about finding the point of interest, by trial and error? what should I be looking out for? Numbers 3-4 I feel more comfortable with but if this problem is too long I can make it into 2 submissions as well.

I just need some guidance with this.

Problem 22.2
The following diagram shows a hand crank with a static load applied to it. You may ignore stress
concentrations. The part is to be made from a ductile steel. Determine what yield strength is required to
achieve a factor of safety equal to 2.
160 mm
300 mm
1000 N
25 mm-dla, round
rod bent into crank
150 mm
