1. The problem statement, all variables and given/known data 2. Relevant equations Net force of the Y vector: -F1 + F2 - weight = 0 3. The attempt at a solution I tried to solve the equation thinking that m could = torque (torque=force X length of lever arm) but I couldn't figure out how to fit in that .025m spot in between the joint and the muscle. Not sure if the equation provided will really help. Any help is appreciated!
