Hello, If I have a shaft that has a section area of .0562 in. sq. and a material yield strength of 60KSI. And I will have the force applied at the top of the shaft pushing down. The shaft will be in a cantilever configuration where the force will be applied .125" from the base of the shaft. How to I calculate the maximum force that can be applied to the shaft before exceeding the yield strength? Also the shaft is not a perfect circle. It is a circle with an radial under cut. Thank you.
