a makeshift close-grip pull-up station. The I beam is anchored at two points (Point A) is at one end, and one anchor point (Point B) is 1.5 m from Point A. The 70 kg man jumps up from the ground and grabs the 3.5 m long beam at the end opposite of Point A. He pauses momentarily before beginning his pullups. Determine the magnitude and direction of the net force acting on the columns supporting Point A and Point B while the man is paused and hanging freely.
