Hey, I'm looking for an explanation of the why we observe T = F * d In the sense of two people applying a force to a lever arm and the person closer to the pivot point requiring more force to keep the torque in equilibrium. I can only find explanations in the sense of work and energy conservation. I know the lever must be observed as conserving energy but how does the lever mechanically magnify the force? Maybe I'm in need of a microscopic understanding? Any in-depth reading on it?
