Question

A shaft has a diameter of 1.5 in and is fitted with a Woodruff key number 1210 (Ch 11, Machine Elements in Mechanical Design, R. Mott). Compute the Torque that "could" be transmitted on the basis of SHEAR and BEARING stress. The material of the key is SAE 1018 COLD DRAWN STEEL. The shaft and the hub materials are stronger that the key material.

Answer 1

To compute the torque that could be transmitted on the basis of shear and bearing stress, we need to consider the dimensions and material properties of the shaft and the key. The formulas for shear stress and bearing stress can be used to calculate the torque.

Step-by-step explanation:

To compute the torque that could be transmitted on the basis of shear and bearing stress, we need to consider the dimensions and material properties of the shaft and the key. Since the key is made of SAE 1018 cold drawn steel and the shaft and hub materials are stronger, we can assume that the key will fail first.

To calculate the shear stress, we can use the formula:

Shear stress = Force / Area

And to calculate the bearing stress, we can use the formula:

Bearing stress = Force / Contact area

By substituting the given values and solving the equations, we can find the torque that could be transmitted.
