Calculate the moments about the bolt when force F1 is removed and F2 is applied.

### Diagram Explanation for Educational Purposes This image illustrates a mechanical setup involving forces and lever arms, commonly used in physics and engineering education to demonstrate principles of torque and equilibrium. #### Components and Notations: - **Dark Rectangular Blocks:** These represent rigid supports or frames that hold the system in place. - **Lever Arms (L-shaped structure):** A set of levers is indicated, pivoted around a point within the system. - **Horizontal Arm (l1):** This lever arm extends horizontally from the pivot point. - **Vertical Arm (h):** This arm is perpendicular to the horizontal arm. - **Short Horizontal Arm (l2):** A smaller horizontal extension from the vertical arm's top. #### Forces: - **F1 (Red Arrow):** A downward force acting on the lever arm. It is represented by a red arrow pointing vertically down. - **F2 (Red Arrow):** A horizontal force acting on the lever arm, shown by a red arrow directed horizontally to the right. ### Concepts Illustrated: - **Torque Calculation:** The forces (F1 and F2) applied at different points and directions on the lever result in torques about the pivot. The effectiveness of each force in causing rotation depends on its magnitude, direction, and distance from the pivot point. - **Equilibrium Conditions:** To achieve equilibrium, the sum of torques around the pivot must be zero. This diagram can be used to explain how to balance the forces and set up equations to find unknown forces or distances. This setup is useful for demonstrating concepts such as mechanical advantage, rotational equilibrium, and the impact of force vectors in mechanical systems.
