Question : 157 of 200

Marks: +1, -0

A circular shaft of diameter d and length l is subjected to a torque T and a bending moment M. The ratio is maximum shear stress to bending stress is:

$T /M$
$T /{2M}$
${2T}/ M$
$T /{4M}$

Validate

Solution:

Bending stress =

{32M}/{πD^3}

Shear stress =

{16T}/{πD^3}

So Shear stress /Bending stress

T/{2M}
