Question

Bad news! When Marcel finds the distance L from the previous part, it turns out to be greater than Lend, the distance from the pivot to the end of the seesaw. Hence, even with Jacques at the very end of the seesaw, the twins Gilles and Jean exert more torque than Jacques does. Marcel now elects to balance the seesaw by pushing sideways on an ornament (shown in red) that is at height h above the pivot. (Figure 3)

With what force in the rightward direction, Fx, should Marcel push? If your expression would give a negative result (using actual values) that just means the force should be toward the left.

Express your answer in terms of W, Lend, w, L2, L3, and h.

The image illustrates a seesaw or lever system with people sitting on either end. The components include:

- A horizontal beam balanced on a central pivot point, known as the fulcrum, depicted as a triangle.
- On the left side of the beam, one person is sitting, and on the right side, two people are sitting together.

Key notations and measurements in the diagram:

- **\( L_{\text{end}} \)**: The distance from the fulcrum to the person sitting on the left end of the beam.
- **\( L_2 \)**: The distance from the fulcrum to the nearer of the two people on the right.
- **\( L_3 \)**: The distance from the fulcrum to the force arrow, labeled \( F_x \), pointing to the right, located slightly to the left of the two people sitting on the right.
- **\( h \)**: The vertical height of the fulcrum, represented by the height of the inverted triangle from its base to the beam.

This setup demonstrates the principle of moments or torque, where balance is achieved when the clockwise moment equals the counter-clockwise moment around the fulcrum.
