- Torque = F x r
For number 6 I answer (a) and for number 7 I answer (d) but I can say I just take a guess.
In question 6, I tried to think about Newton 3rd law. The force exerted by each arm on the other is equal so assuming the distance from the point where the force acts to the pivot is also the same, the torque is the same.
But in question 7, my reasoning for question 6 seems absurd. To win, I need to exert bigger torque so the arms can rotate in the direction I want to but it seems to contradict the reasoning in question number 6 so I am confused.
Thanks
