Belt - torqque and power transmission

The torque available at the driven wheel or pulley (a) can be expressed as

T = (F2 - F1) ra                        (1)


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)


P = power transmitted (watts)

ωa = angular velocity (rad/s)
