You have a person doing a bench press. Their hands are equidistant apart and they are centered on the bar - each hand about 1.5 feet from center of the bar. The bar weighs 45 pounds.
In example 1 there are two 45 pound weights on each side at 2.5-3 feet each from the center (lets say each weight is 3 inches wide).
In example 2 there are nine 10 pound weights on each side starting at 2.5 feet again and then ending 27 inches later.
What are the forces that cause example to to feel heavier and is there any way to calculate it.
