Question

A force of 50.0 N is applied at an angle of 30.0 degrees from the end of a 2.0 m long bar. Calculate the torque applied to the bar from the location of the force to the end of the bar. Show all steps. Thanks

Answer 1

If a force F is applied at an angle to the end of a bar, then torque is given by the product of force (F) and the perpendicular distance between the line of action of force and the point of rotation (r). See the figure below

The rod is rotating from the point A. So r = 2m. Now the torque is given by

So the torque applied to the bar is 50Nm.
