Question
**Educational Content:** **Topic:** Mechanics - Equivalent Couple Moment **Problem Statement:** - Replace the horizontal 266-N force acting on the lever by an equivalent couple moment (N·m) at point O. - Given: - φ (phi) = 34° - L = 114 mm - The direction of positive moment is counter-clockwise. **Diagram Explanation:** - The diagram illustrates a lever pivoted at point O. - There is a 266-N horizontal force (P) acting on the lever. - The lever makes an angle φ = 34° with the horizontal axis. - The length of the lever is L = 114 mm. - The force is applied at the end of the lever, moving to the right. **Objective:** - Determine the equivalent couple moment in N·m at the pivot point O that can replace the given force's effect on the lever. The concept applies principles of moments and equilibrium, ideal for understanding torque and mechanical leverage.
