There are similar 1st and 2nd laws for torques as there are for forces, but it doesn’t seem like this applies to N3L? For example, lets say i have force acting on an object about some pivot. That object will apply an equal force about the same pivot, at equal lever arm, back. So there it seems like if the forces are in line, acting on the same pivot point, there is an equal and opposite torque. However, if i have two gears, A and B, with A being half the diameter of B, as A drives gears B, there are contact forces between the gears and since there are different lever arms and point of rotations, the torques created are not equal. SO i am wrong to say that N3L doesn’t apply to torque? Thanks for the clarification.
