1. The problem statement, all variables and given/known data The connected bar BC is used to increase the lever arm of the crescent wrench as shown.If a clockwise moment of Ma=120 N*m is needed to tighten the nut at A and the extension d=300mm, determine the required force F in order to develop this moment. 2. Relevant equations M=Fd 3. The attempt at a solution Wrote the x length of BC by multiplying 0.3m*cos30, then took the x-y coordinate system through the AB(for x) and perpendicular to the AB(for y).Tried to find the angle that F makes with the x-y (ABCx), found it as 45, but the result is not correct.
