Question

When opening a door, you push on it perpendicularly with a force of 57.0 n at a distance of 0.470 m from the hinges. what torque (in n·m) are you exerting relative to the hinges? (enter the magnitude.)?

Answer 1

Torque = force * distance from axis of rotation. Multiply. If it's not perpendicular, you multiply that with the sine of the angle between the force and the perpendicular direction. T= 0.470*57*Sin 90 = 26.79 N
