Belts - Power Transmission and Efficiency
The torque available at the driven wheel or pulley (a) can be expressed as
T = (F2 - F1) ra (1)
where
T = torque (Nm)
F = force (N)
r = radius of wheel or pulley
The available power can be expressed as
P = T ωa = (F2 - F1) ra ωa (2)
where
P = power transmitted (watts)
ωa = angular velocity (rad/s)
