Given: Flat rolled sheets are produced in wide rolling mills, but many products are manufactured from strip stock. The below figure is a free-body diagram of a shaft for a short slitting line where a single blade is placed in the center of the shaft and a motor drives the shaft through a pulley at the far right end. Find: The shaft diameter If the maximum shear stress is 40 MPa and the largest gage sheet causes a blade force of 2000 N,
