1.A flat belt drive system is to be designed for an application in which the input motor shaft speed (driving pulley) is 1725 rpm, the driven shaft speed is to be approximately 960 rpm, and the power to be transmitted has been estimated as 3.0 horsepower. The driven machine has been evaluated and found to have the characteristics of moderate shock loading during operation. The desired center distance between driving and driven pulleys is approximately 18 inches.

a. If -inch-thick polyamide belt material were chosen for this application, what belt width would be required?

b. What initial tension would be required for proper operation?
