How much force is required to produce a 90 N⋅m torque on an object about the point about which the object can rotate? The distance between the point where the force is applied and the point about which the object can rotate is 2.5 m.
How much torque is produced by a 30 N force acting on an object at a distance of 0.15 m from the point about which the object can rotate?
A spanner is used by a mechanic to tighten a nut. The spanner is 20 cm long and to tighten the nut it must apply a torque of 12 N⋅m. What force must the mechanic apply to the end of the spanner that is opposite to the end that tightens the nut? The spanner turns through a horizontal circle to tighten the nut.
