Torque Calculator

90 degrees is a force applied square to the arm, which is the usual case.
From the pad manufacturer’s data sheet. Brake torque is not reported without it.

How this is worked out

3 steps
  1. tau = F r sin(theta) = 100 N x 0.5 m x sin(90 deg) = 50 N m
  2. omega = 2 pi x 3000 / 60 = 314.15927 rad/s.
  3. P = tau omega = 50 x 314.15927 = 15707.96 W = 15.708 kW = 21.0647 hp.
