What is the tension of the string of this figure description? A 60 kg person is suspended in the air from a rope attached to a pulley, with a 100 kg mass attached to the other end that touches the ground. T= 588 N because F=ma. ma=(60 kg * 9.8m/s2) correct! The person weighs m = 60 kg, so it takes 60 kg of weight (mg) to keep him suspended.
If there is no movement, the tension on the rope is therefore 60g.
The next step is to determine if there is movement.
If the pulley is frictionless, then the tension on each side of the pulley is the same, T=60g.
At the mass of 100kg, the tension of 60g being less than 100g, the mass of 100kg will remain stationary.
Note: If the masses do not stay still, the resulting acceleration will change the tension of the string.
