Hello, I have a question regarding the concept of torque and reference frames. Say for example I have a rod of length L and that the rod has it's right side anchored to act as a pivot point. Now let's say that I input a force on the left side of the bar in an upward direction. Assuming that positive torque corresponds to clockwise rotation, the torque is the force x L (and is positive) with respect to the right pivot point.. Now lets say I do this same experiment, but this time, I want to use a frame of reference such that the left side of the rod appears to be anchored. From what I can deduct, the torque as seen by this virtual pivot point will have the same torque magnitude as the last experiment, except it will be negative now... Is my reasoning correct? I'm kind of just curious and don't know if phenomenon has a specific name. Thanks for any help!
