    Rotational Equilibrium and Normal Forces

    Thanks! That really clears things up for me. Seems so obvious, now that you say that.

    Rotational Equilibrium and Normal Forces

    Maybe that picture wasn't the best to demonstrate my problem. Here's another. Why is it that for the diagram on the right (person standing on the floor), you can consider the normal force of the person, but with the diagram on the left (person on a see-saw), you don't consider the "normal...

    Rotational Equilibrium and Normal Forces

    Hi, The question I have is not for a numerical answer but for clarification. Some of the questions involving torque/rotational equilibrium describe a person standing on a plank. I know that the gravitational force of the person on the plank needs to be considered for translational and...
