Topic module

Levers, Gears and Pulleys

Use direction, distance and mechanical-advantage relationships in common mechanisms.

Long-form learning

Concept to Risk to Memory to Check-up

Build an accurate method first, add controlled pace second, and follow the instructions shown in the official assessment for every timed section.

Core concepts

Concept 1

Moments and levers

Exam cue: Mark the pivot or contact point, follow the transmission path, and compare effort with load.

Concept 2

Gear trains

Exam cue: Check both direction of movement and the speed, distance or force trade-off.

Concept 3

Pulley systems

Risk pitfalls and guardrails

Tracking direction correctly while overlooking the associated mechanical trade-off.
