QUESTION:
The 304 stainless steel tube has a thickness of 10 mm. If the allowable shear stress is \(\tau_{\text {allow }}=80 \mathrm{MPa}\), determine the maximum torque T that it can transmit. Also, what is the angle of twist of one end of the tube with respect to the other if the tube is 4 m long? The mean dimensions are shown.
ANSWER:Step 1 of 5
The equation for average shear stress at a non circular tube as in our case is given by equation 5-18 and is :
\(\tau_{a v g}=\frac{T}{2 t A_{m}}\)
The only unknown in the above equation is the mean area \(A_m\) which is
\(A_{m}=0.03 \cdot 0.07=0.0021 \mathrm{~m}^{2}\)
