Current Attempt in Progress

A solid circular shaft made of steel is subjected to a torque $T=760lb*ft$ and a tensile axial force $P=11500lb.$

Assume that the steel has a yield strength of ${}_Y=30,000$ psi. Use

$($a$)$ the maximum$-$shear$-$stress theory and

$($b$)$ the maximum$-$distortion$-$energy theory

to determine the required diameter of the shaft so that the shaft does not fail by yielding.

Part $1$

Correct Answer $($Used$)$

Incorrect

Determine the normal stress in terms of the diameter d of the shaft.

Answer:

$=l\frac{b}{d^2}$
