A heavy bank-vault door is opened by the application of a force of 3.0 10^2N directed perpendicular to the plane of the door at a distance of 0.80 m from the hinges. What is the torque?

300 N * m ?!?!?

• physics -

300 N * .8 m

Torque (or "moment of force") is force component perpendicular to the direction to the fulcrum(hinge) times distance to the fulcrum
