Question

A bolt is to be tightened with a torque of 8.0 N*m. If you have a wrench that is 0.35 m long, what is the least amount of force you must exert?
the equation for this problem is
t=Fr sinbeta, but the sin is not given What am I suppose to do?
bobpursley
force*arm=torque

Now on the angle, don't we move wrenches at 90 degrees?
