Principle of Moments
To have no translational acceleration, all forces must be balanced.
Unbalanced moments
Can lead to rotational motion.
Clockwise moments
Balance with anti-clockwise moments for no rotation.
Application of Principle of Moments
Forces applied in the same direction cancel out turning effects.
Net moment
Created by forces applied in opposite directions for rotation.
Equilibrium
Clockwise moments equal anti-clockwise moments.
Problem Solving
Using the Principle of Moments to find unknown quantities in equilibrium situations.
Calculations
Involving clockwise and anti-clockwise moments for equilibrium.
Equating Moments
Clockwise moments equal anti-clockwise moments for balance.
Center of Mass
Can be away from the center in an irregular rod, causing tilting towards the side with the center of mass.
Finding Center of Mass
Principle of moments helps find the center of mass in irregular objects.
