Problem
The handle of a door is 0.75 m from the hinge. Calculate the torque about the hinge when a perpendicular force of 12 N is applied on the handle.Intuitive explanation
Torque measures how effectively a force causes rotation around a pivot point—in this case, the hinge. The key insight is that torque depends on two things: how hard you push (the force) and how far from the hinge you push (the lever arm). Since the force is already perpendicular to the door, you can multiply them directly without worrying about angles.
