In a flat belt drive, a 3-inch-diameter pulley (input) drives a 12-inch-diameter pulley (output) with a polyamide F-1 belt (allowable tension per unit width: 35 lbf/in). The belt width is 8 inches. The nominal power is 1,2 hp with the input pulley rotating at 600 rpm. What is the maximum allowable tension (in lbf) for this belt, if the velocity correction factor Cv is 1.0? Table 17-4: Pulley Correction Factor C, for Flat Belts Material Polyamide, F-0 Polyamide, F-1 Polyamide, F-2 O A. 196 OB. 258 OC. 269 OD. 280 O E.
