3 cards from this section. Quick, good the night before a test.
Define torque and provide its formula.
Remember how force and distance from the pivot relate to rotation.
What is the unit of torque?
Think about how torque relates to force and distance.
What determines the torque on a lever arm?
Think of the physical examples of using levers.
True or False: An increase in distance from the pivot will always increase the torque if force is constant.
Visualize applying the same force further down a lever.
A door with a width of 0.9 m has a handle located 0.8 m from the hinge. If a force of 20 N is applied perpendicular to the door at the handle, what is the resulting torque about the hinge?
Use the torque formula with distance to pivot.
If the moment of inertia of a solid disc is given by I = 1/2 MR², calculate the angular acceleration produced when a torque of 10 N·m is applied to a disc with a mass of 5 kg and radius of 0.5 m.
Don’t forget to find I first before solving for α.
