Pablo and Juna carry a load weighting 720 Newton on a pole between them.
A) If the pole is 2.0 meter long and the load is 0.50 meter from Pablo, (Ignore the weight of the pole,) calculate what force does each person support?
B) If the weight of the 120 Newton pole is considered, calculate what force does each person support?
