Study Notes
Principle of Moment
- The principle of moment states that the total counter-clockwise moment is equal to the total clockwise moment when a body is in equilibrium.
- This principle applies to systems in equilibrium, where the total counter-clockwise moments equal the total clockwise moments.
Examples of Principle of Moment
- A beam balance and see-saw work on the principle of moment.
- Example 1: If a system is in equilibrium, then the total counter-clockwise moments equal the total clockwise moments.
- This can be mathematically represented as: F1 x d1 = F2 x d2.
- Example 2: If a system has multiple forces, the total counter-clockwise moments equal the total clockwise moments.
- This can be mathematically represented as: F1 x d1 + F3 x d3 = F2 x d2.
Problem-Solving using Principle of Moment
- A 6m long seesaw is pivoted at its center, and a child with a weight of 200N sits at one end.
- To balance the seesaw, the friend with a weight of 300N should sit at a distance from the pivot point that satisfies the principle of moment.
- Mathematically, this can be represented as: 300 x d1 = 200 x 3, where d1 is the distance from the pivot point.
- Solving for d1, we get d1 = 2m, which is the distance from the pivot point where the friend should sit to balance the seesaw.
