You have a seesaw with 2 people on each end. the seesaw is on a pivot. label the forces in a free body diagram acting on the seesaw. Its online and I tried a force down on each end but then the pivot it keeps saying is wrong. I tried a force up from the pivot, a moment, force down, everything.

One force down at each end, and a force up at the pivot equal to the sum of the two end forces should be all you need in the free body diagram.

To correctly label the forces in a free body diagram for a seesaw, you need to consider the forces acting on each individual person as well as the pivot point. Here's how you can break it down:

1. Start by drawing a diagram of the seesaw, representing it as a straight line with a pivot point in the middle.

2. Label the two individuals on each end of the seesaw as Person A and Person B. On your diagram, draw arrows representing the downward force of their weight acting at their respective positions.

3. Now, let's consider the forces acting on the pivot point. Since the seesaw is balanced and not accelerating vertically, the sum of the vertical forces acting on the pivot must be zero. Therefore, draw an upward force arrow at the pivot point to represent the upward force exerted by the pivot to counterbalance the combined weight of Person A and Person B.

4. Additionally, draw arrows to represent the upward reaction forces exerted by the pivot on each person at their respective positions. These reaction forces are equal in magnitude and opposite in direction to the downward forces exerted by Person A and Person B.

By following these steps, you should have a free body diagram that correctly illustrates the forces acting on the seesaw and the pivot.
