A disk is rotating on a horizontal axis, going from bottom to top. Answer the following questions if you pull down at A and push up at B along the axis of the disk.

What is the direction of the torque acting on the disk?

A figure or better description is needed. Where are A and B? If the axis is horizontal, "up and down" and "along the axis" are contradictory.

To determine the direction of the torque acting on the disk when you pull down at point A and push up at point B, we need to consider the right-hand rule for torque.

1. Extend your right hand and align your thumb with the rotational axis of the disk, pointing upwards (from bottom to top in this case).
2. Curl your fingers towards the direction of your pull or push force. In this case, curl your fingers from A to B.

By following these steps, you will notice that your fingers curl in a counterclockwise direction (opposite to the rotational motion of the disk). Therefore, the direction of the torque acting on the disk is counterclockwise.
