How to find angular momentum from a graph

I have been give a time v torque graph and asked to determine the change in angular momentum. My textbook does not go over this and my professor hasn’t cover this.

Why is less force required to open a door when we apply a force at a greater distance from the hinge?

I know that the magnitude of a torque increases with the distance from the axis of rotation. What is the reason of that : how can a force exert a greater torque when the force is applied at a... more

Why does an unhinged body rotate about its centre of mass?

If a force is applied to a body which does not act through its centre of mass, it rotates about its centre of mass and not any other point. Why?

Torque applied to the end of an axle will result in the same torque being felt at the other end of the axle.

Will changing the diameter or length of the axle change this relationship?
