1. The problem statement, all variables and given/known data Find the force 'p' and angle 'alpha'. 2. Relevant equations m=rXf 3. The attempt at a solution I calculated the couple moment by using M=rXf, I plugged r=12 and f=8 and the answer come out to be 96 lb.m. After finding the couple moment I am stuck now, I could not figure what I am suppose to do with the vectors A and B to calculate p and alpha, do I have to use this formula again M=rXp, if yes the what value I should for r?
