Question: 4 A 2 0 mm diameter roller is in contact with a plate - cam surface whose width is 1 2 mm and the radius

4 A 20 mm diameter roller is in contact with a plate-cam surface whose width is 12 mm and the radius of curvature of the cam surface is 85 mm . If the Hertz compressive stress is not to exceed 2000 MPa , determine the maximum load that can be applied.
If the follower has the plane flat surface keeping other parameter same as above, then determine the maximum load that can be applied.
