1. The problem statement, all variables and given/known data a) What is the length, rmr_m, of the moment arm of the force F→F_vec about point p? b) Find the torque τtau about p due to F→F_vec. Your answer should correctly express both the magnitude and sign of τ. 3. The attempt at a solution a) I'm inclined to state the answer as -rsinΘ but apparently the answer is r sin Θ. Is there a reason why the sign is positive?
