This torque is clockwise and they have considered ccw to be positive. So you need to add a negative sign. Ans: -L 1 w .

remaining Marcel wants the seesaw to balance, which means that there can be no angular
acceleration about the pivot. For the angular acceleration to be zero, the sum of the torques about
the pivot must equal zero Part C
Solution
You are correct in answering that the torque is L 1 w. This torque is clockwise and they have
considered ccw to be positive.
So you need to add a negative sign.
Ans: -L 1 w
