Slide 15 "Note: A rod has no mass, so there is no reaction force of the rod on the man, only reaction forces from the pivots." This isn't right. We ignore the reaction force of the rod on the man as we are only considering forces acting on the rod. If we were to consider the forces acting on the man we would draw and the reaction force of the rod on the man.

Very useful powerpoint with good examples
