[From: ] [author: ] [Date: 12-02-12] [Hit: ]
any help is much appreciated!90 = F*0.......
The bolts on a cat wheel require tightening to a torque of 90 n*m. If a 20 cm long wrench is used, what is the magnitude of the force required when the force is perpendicular to the wrench?
a.) 10 N
b.) 230 N
c.) 450 N
d.) 20 N

Need to know this for my physics test, any help is much appreciated! :)

Torque is 90Nm and not 90 nm

Torque = F * d

90 = F*0.2
F = 450 N

Answer is C)
