Rotational equilibrium

What You'll Learn

Identify when an object is in rotational equilibrium with balanced torques

Calculate torque using force, distance from pivot, and perpendicular orientation

Apply the equilibrium condition that clockwise and counterclockwise torques must be equal

Determine unknown forces or distances by balancing torque equations

Recognize how center of mass affects torque calculations for uniform objects

What You'll Practice

Balancing rods with multiple masses at different distances from a pivot

Calculating support forces on shelves with distributed weights

Finding unknown distances needed to achieve rotational equilibrium

Working with torques from gravity acting on multiple objects

Why This Matters

Rotational equilibrium is essential for understanding how structures stay balanced, from bridges and building supports to levers and seesaws. Mastering torque calculations prepares you for engineering, physics, and any field involving mechanical systems and structural stability.
