## Homework Statement

Given a 1.5” output shaft, a 80-90 ksi yield strength.

Neglecting limitations of keys or gear reducer what is the maximum HP that could be transmitted by the 1.5” shaft

## Homework Equations

Torque = (63025*H)/n H is HorsePower and n is RPM

Force = Torque/radius

## The Attempt at a Solution

If I can find the maximum force then the maximum torque/HP can be calculated using the above equations. I m not sure how to calc the max shear force using the given data.
