Unformatted text preview: shear stress theory and distortion energy theory. A -in-drive socket wrench shown below is made of a low-alloy steel of S y =90 ksi. A 180-lb mechanic puts a prop under the extension and then stands on the end of the handle to loosen the obstinate bolt. Is the mechanic close to yielding the handle or the drive? Use max shear stress theory for predicting the onset of yielding....
