A horizontal uniform bar of mass 2kg and length 3.0 m is hung horizontally on two vertical strings. String 1 is attached to the end of the bar, and string 2 is attached a distance 0.65m from the other end. A monkey of mass 1kg walks from one end of the bar to the other. Find the tension T1 in string 1 at the moment that the monkey is halfway between the ends of the bar.
For the bar to experience no net force, what must be the tension T2 in string 2 when the monkey is halfway between the ends of the bar?
