Maximum Stress/Torque for rotating shaft

  1. Sep 16, 2011 #1
    1. The problem statement, all variables and given/known data

    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


    2. Relevant equations

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

    Force = Torque/radius

    3. 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.

    You need an equation that relates torque and maximum shear stress in a rotating shaft. That equation should be given (or derived) in your class. If that's not the case (which would be very odd), you can always try Google.
