Magnitude of force?

1 ⤊

The bolts on a car wheel require tightening to a torque of 90(N)m. If a 30 cm long wrench is used, what it the magnitude of the force required when the force is perpendictular to the wrench?

Torque=Force*Perpendicular distance from the centre.
Therefore,
90Nm=force*0.3m
or F=90/0.3
or F=300N

Torque = force times distance to center of rotation. The force you need will be 90/0.3 (90 N*m / 0.3m)
