The 55hp reducer motor can turn at 1050 revmin The shaft has

The 5.5-hp reducer motor can turn at 1050 rev/min. The shaft has a diameter of 5/8 in. Determine the maximum shear stress in the shaft. Express your answer to three significant figures and include appropriate units.

Solution

There will no stress development in the shaft

because stress is a result of resistance

But here , there is no resistance ,

Here shaft is given some torque and it is freely rotating , ther is no counter torque which can bring twist in shaft so ther is no shear stress developed

So answer will be 0.000
