"Torque and Equilibrium." If two children are on the seesaw, is it possible that the lighter of the two could sit further away from the center and bring his side closer to the ground. Explain your answer.
- In a seesaw, the side which has higher torque is on the ground.
- Therefore, in order for the lighter child to bring his side closer to the ground, s/he must at least make his torque equal to the torque of the heavier child on the other side (Equilibrium condition)
- Now, Torque = Weight of child x Distance from centre
- So, to increase torque, the child must increase the distance from the centre until the child's torque is equal to the heavier child's torque
