A Hollow Aluminum Shaft $\left( G = 27 \mathrm { GPa } , d _ { 2 } = 96 \mathrm {~mm} , \text { and } d _ { 1 } = 52 \mathrm {~mm} \right)$

question 5

Multiple Choice

A hollow aluminum shaft ( $\left( G = 27 \mathrm { GPa } , d _ { 2 } = 96 \mathrm {~mm} , \text { and } d _ { 1 } = 52 \mathrm {~mm} \right)$ has an angle of twist per unit length of $1.8^{\circ} / \mathrm{m}$ due to torques T. The resulting maximum tensile stress in the shaft is approximately:

• A) \(38 \mathrm { MPa }\)
• B) \(41 \mathrm { MPa }\)
• C) \(49 \mathrm { MPa }\)
• D) \(58 \mathrm { MPa }\)
