A polyamide A-3 flat belt is used to transmit 15 hp under light shock conditions where K = 1.25, and a factor of safety equal to or greater than 1.1 is appropriate. The pulley rotational axes are parallel and in the horizontal plane. The shafts are 8.5 ft apart. The 6-in driving pulley rotates at 1750 rev/min in such a way that the loose side is on top. The driven pulley is of 18-in diameter. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. With the tension from part a, find the belt width b that exhibits nfs = nd=1.1. (You must provide an answer before moving to the next part.) The belt width b will be in.
