- Statics and Principles of Moments A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left side. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, another child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did in part b, the plank would need to move on the seesaw…3.
