Support arm

    1. The problem statement, all variables and given/known data
    Just looking for a general response - calculating required torque when there is a supoprt arm like in the attached doc. If there was no arm ... it's just F*d, but I guess the arm supports some of that force, so less torque is required?

    2. Relevant equations

    3. The attempt at a solution

    I didnt get your diagram, however, if there is an arm of total mass m hanging from a hinge with constant linear mass density of length x, and there is a support arm at a distance y from the hinge, then the total the torque about the hinge would be:
