A machinist is using a wrench to loosen a nut. The wrench is 25.0 cm 17.0 N long, and he exerts a 17.0N force at the end of the handle at 37° with the 37° handle (a) What torque does the machinist exert about the center of the nut? (b) What is the - 25.0 cm- Nut maximum torque he could exert with a force of this magnitude, and how should the force be oriented?
