1. The problem statement, all variables and given/known data In order to pull out the nail at B, the force F exerted on the handle of the hammer must produce a clockwise moment of 590 lb⋅in about point A.(Figure 1) Determine the required magnitude of force F. 2. Relevant equations 3. The attempt at a solution M=590lb*in -590= -Fcos(30)(18)-Fsin(30)(5) I'm not sure how to deal with F. I know it's simple if given the force to determine the moment but I'm a bit stumped trying to go the other way.
