Question

A torque of 180Nm is caused by a force perpendicular to a beam acting at a point 1.6m from the fulcrum. Caculate the magnitued of the force.

Answer 1

Torque = Force * Perpendicular distance.
180 Nm = F * 1.6.
F* 1.6 = 180.
F = 180/1.6 Use your calculator.
F = 112.5.
Force is 112.5 N. That's it.
