🧠 Memory Aid
M = Fd — "MOMENT = FORCE × DISTANCE":
Think of opening a door: you always push near the edge (far from pivot/hinges), not near the hinge. Maximum distance = maximum moment = easiest to open. Pushing near the hinge would be terrible — tiny distance, tiny moment.
Clockwise vs Anticlockwise — use a clock face: Imagine the object as a clock. Which way would the force rotate it — the same direction as clock hands (clockwise) or opposite (anticlockwise)? Label moments accordingly.
Principle of moments shortcut: "Clock = Anti-Clock" — the clockwise moments must equal the anticlockwise moments for balance.
