1. The problem statement, all variables and given/known data 2. Relevant equations included in the problem 3. The attempt at a solution included in the problem. As you can see I already solved for the force part of the problem. What I'm having trouble with is what to do with the 40mm and 20mm of the problem. Do I even have to included it in the problem. If so where do I. Do I have the right step up for the couple part?
