Chapter 6.2
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
1
Balancing rods with multiple masses at different distances from a pivot
2
Calculating support forces on shelves with distributed weights
3
Finding unknown distances needed to achieve rotational equilibrium
4
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.
