For a lever to maintain equilibrium, which condition must be satisfied?

• A. Clockwise moments must equal zero
• B. Anti-clockwise moments must equal zero
• C. Clockwise moments must equal the anti-clockwise moments
• D. Clockwise moments must be greater than anti-clockwise moments

Answer: (C)

For a lever to maintain equilibrium, the condition that must be satisfied is that the clockwise moments must equal the anti-clockwise moments. This principle is based on the concept of moments (or torques), which measure the tendency of a force to cause rotation about a pivot point. In equilibrium, there should be no net torque acting on the lever, which means that the forces causing rotation in one direction (clockwise) must be balanced by forces causing rotation in the opposite direction (anti-clockwise). When this balance exists, the lever will not rotate and will remain in a stable position. This balance is essential in many practical applications, such as balancing scales or ensuring that beam loads are distributed evenly. By satisfying this condition, it ensures that the lever functions effectively without tipping or rotating due to an imbalance of forces.
