A person carries a plank of wood 4.3 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at 0.65 m from the end of the plank with force F2 . If the plank has a massof 16.4 kg and its center of gravity is at the middle of the plank, what is the magnitude of the force F1?
