Torque and Rotational Dynamics
What is torque a measure of?
In the context of torque, what is the lever arm?
A force is applied to a door handle. Which scenario will result in the greatest torque about the hinges?
A force of 20 N is applied at an angle of 30 degrees to a wrench that is 0.3 m long. What is the magnitude of the torque?
If the force applied to a wrench is doubled, and the length of the wrench is halved, how does the torque change?
Three forces are applied to a rigid beam that can rotate around a fixed axis. Force N is applied at a distance of 2 m and an angle of 90 degrees, force N is applied at a distance of 4 m and an angle of 30 degrees, and force N is applied at a distance of 1 m and an angle of 45 degrees. All...
A mechanic is trying to loosen a bolt. They apply a 50 N force to a wrench at a 60-degree angle, 0.2 m from the bolt. If they need to produce a torque of 10 to loosen the bolt, how much additional force do they need to apply, keeping the angle and distance the same?

Which of the following diagrams correctly represents the forces acting on a seesaw that is balanced with two people of different weights on either side?
A uniform bar is pivoted at its center. A force is applied at one end of the bar. In which direction should the force be applied to create a clockwise torque?
A seesaw is balanced with a child on each end. One child weighs 200 N and sits 1.5 m from the pivot. If the other child sits 2 m from the pivot, what is their weight?
