Flat and round belt drives
A 7-in wide polyamide F-1 flat belt is used to connect a 2-in diameter pulley to drive a larger pulley with an angular velocity ratio of 0.5. The center-to-center distance is 9 ft. The angular speed of the small pulley is 2000 rev/min as it delivers 2 hp. The service is such that a service factor of Ks of 1.25 is appropriate.
Find Fc, Fi, (F1)a, and F2, assuming operation at the maximum tension limit. (You must provide an answer before moving to the next part.)
The value of Fc is lbf.
The value of Fi is lbf.
The value of (F1)a is lbf.
The value of F2 is lbf.
