Calculate the maximum allowable torque (in-lbs). A solid steel shaft is made from AISI 1045 steel, with a 9.0" diameter and length of 44". The maximum allowable shear stress on the material is 6200 psi. Based on the answer above, what is the required RPM if this shaft needs to transmit 4500 HP at the maximum allowable torque?
Please don't copy from online.
Compare the weights of equal lengths of hollow and solid shafts to transmit a given torque for the same maximum shear stress if the inside diameter is 2/3 of the outside.
Design a hollow circular steel shaft to transmit an applied torque of 360,000 in-lbs. The allowable shear stress is 6,000 psi and the inside diameter is to be 0.6 times the outside diameter.
Not sure how to solve this problem, please walk me through the process step-by-step and write clearly. Thanks in advance.
