A 4-in-wide polyamide F-2 flat belt is used to connect a 3-in-diameter pulley to drive a larger pulley with an angular velocity ratio of 0.3. The center-to-center distance is 10 ft. The angular speed of the small pulley is 1500 rev/min as it delivers 3 hp. The service is such that a service factor Ks of 1.3 is appropriate. a) Find Fc, Fi, (F1)a, and F2, assuming operation at the maximum tension limit. b) Find Ha, L, and the safety factor nfs. c) Find the dip
