Question

how can a small boy balance a big boy on a sea-saw? Show with a diagram.

fast please......

Answer 1

Answer:

The small boy should sit at the far end and the big boy near the middle. Then moments of both of them about the middle will become equal and both will balance each other.

Answer 2

Answer:

The small boy balance on a sea saw by putting equal weight on both ends or maintaining the center of gravity.

Explanation:

physics behind sea saw:

• A seesaw has a pivoting factor withinside the center of the board. When an item is balanced on a pivoting factor, the turning forces on every aspect need to same as the turning pressure on the alternative aspect.
• This method that on one aspect of the pivot, the pressure needs to be transferred in a counterclockwise movement, and on the alternative aspect, the pressure needs to be transferred in a clockwise movement. For the board to be absolutely degree at the pivot factor, the individual or item needs to same the identical weight of the alternative aspect.
• However, in case you locate a heavier item on one aspect and location it towards the pivot factor, stability may be achieved. This is due to the fact the middle of the pivot can maintain greater weight than the alternative sides.

For example, if a younger lady had been to take a seat down at the cease of a seesaw and a heavier guy had been to take a seat down on the alternative aspect, the person could take a seat down towards the pivot factor than the little lady,
