Machine Design
The ratio of belt tensions (p1/p2) considering centrifugal force in flat belt is given byWhere m = mass of belt per meter (kg/m)v = belt velocity (m/s)f = coefficient of frictiona = angle of wrap (radians)

(P1 - mv²)/ (P2 - mv²) = eᶠα
P1 / P2 = e–ᶠα
P1 / P2 = eᶠα
(P1 - mv²)/ (P2 - mv²) = e–ᶠα
