Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video.
A pulley of diameter D = 720 mm is mounted on a shaft that has a diameter of d = 80 mm. The pulley is prevented from rotating
relative to the shaft by a shear key. The cross section of the shear key is square with dimension a = 10 mm. The length of the shear key
(i.e., the dimension into the screen) is 110 mm.
The allowable shear stress in the shear key is 200 MPa. If T2 = 0.20T1, what is the maximum allowable belt tension T1?
