Assumesuitable approach and over-run and specific energy of mild steel as 5 Ws/mm3.The blade on a typical table saw rotates at 3100 revolutions per minute. Calculate the linear velocity in miles per hour of one of the teeth at the edge of the 10 inch diameter blade.A lathe having a 5-step pulley is driven by a belt, assumed to be crossed, from a pulley of the same size on the countershaft. The countershaft is to have a constant speed, and the lathe is to have speeds of 60 rpm and 135 rpm when the belt is on the steps either side of the center step. If the minimum speed is 40 rpm and the smallest diameter is 4 in., find theproper speed of the countershaft, maximum speed of the lathe, and the diameter of all steps on the pulleys.
