1. Torque  If an unbalanced force acts on an object at rest, and: 1)the force does not act along the center of mass of the object, 2)the object is fixed at a certain spot, 3)another force is also acting, but at a different spot on the object, OR the object will rotate about some axis

2. Torque The torque that a force exerts on an object is found by: rotation axis (moment arm) (cross product)

3. The force on the wrench is 105 N and is applied 18 cm from the rotation axis of the bolt. The hand pushes perpendicular to the wrench handle. The torque exerted on the wrench by the hand is…

4. If the maximum radius of the bolt is 1.30 cm, the minimum force the wrench will exert on the bolt would be… The wrench applies the same torque to the bolt.
