A machinist is using a wrench to loosen a nut. The wrench is 25.0 {\rm cm} long, and he exerts a 17.0-{\rm N} force at the end of the handle at 37 ^\circ with the handle


What is the magnitude of the torque does the machinist exert about the center of the nut?

What is the direction of the torque in part (A).

What is the maximum torque he could exert with this force?
How should the force mentioned in part (C) be oriented ?

torque = force* perpendicular distance from the axis of rotation
τ=force∗r where r is the perpendicular distance from the axis of rotation 


direction is upwards 


maximum torque can be applied if the  direction of force is perpendicular to the axis of rotation
