Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

When climbing into your childhood tree house you realize someone has left a
weight of mass m =
3.0 kg in the middle of the trapdoor, 0.60 m from the
hinges. You apply an upward force of 75 N at a distance R
hinges. If the door has a mass of 10 kg, what is the angular acceleration of the
door and the weight? Assume you can treat the door as a rod, that the block
1.2 m from the
rotates with the door, and that the weight is very small (a point particle).
Pick the correct answer
0.31 rad/s?
2.3 rad/s?
0.0 rad/s?
2.8 rad/s?
14 rad/s?
