The principle of moment, also known as the principle of torque or the law of moments, states that for a system to be in rotational equilibrium, the sum of the clockwise moments must be equal to the sum of the anticlockwise moments. In simpler terms, it means that if an object is balanced and not rotating, the total torque or turning effect acting on it must be zero.
Imagine a see-saw or a lever with two people sitting on opposite ends. If the see-saw is balanced, it means that the moments or torques exerted by the two individuals are equal and opposite. This principle applies to any object in rotational equilibrium, whether it's a simple lever or a more complex system.
In summary, the principle of moment deals with the concept of balance and equilibrium in rotating systems and states that the sum of clockwise and anticlockwise moments must be equal for the object to remain in a state of balance.
A cataract is a cloudy lens. The lens is positioned behind the colored part of your eye (iris). The lens focuses light that passes into your eye, producing clear, sharp images on the retina — the light-sensitive membrane in the eye that functions like the film in a camera.
As you age, the lenses in your eyes become less flexible, less transparent and thicker. Age-related and other medical conditions cause proteins and fibers within the lenses to break down and clump together, clouding the lenses
