A polyamide A-3 flat belt 6 in wide is used to transmit 15 hp under light shock con-ditions where Ks = 1.25, and a factor of safety equal to or greater than 1.1 is appro-priate. The pulley rotational axes are parallel and in the horizontal plane. The shafts loose side is on top. The driven pulley is 18 in in diameter. See Fig. 17-10. The fac-tor of safety is for unquantifiable exigencies. (a) Estimate the centrifugal tension Fc and the torque T.
(b) Estimate the allowable F1, F2, Fi and allowable power Ha.
(c) Estimate the factor of safety. Is it satisfactory ?
