Lesson Details
Key learning points
- In our bodies, levers are made from bones, joints, and muscles working together.
- A lever consists of a fulcrum (joint), the effort (muscle creating the movement) and the load (weight or resistance).
- There are three lever systems in the human body.
Common misconception
When drawing levers the body part needs to be included.
A lever will always be drawn using four shapes.
Keywords
Lever - a rigid bar (bone) that rotates or pivots around a fixed point (fulcrum) when a force (effort) is applied to move a resistance (load)
Fulcrum - the fixed point around which a lever pivots or rotates
Effort - the force applied to a lever to move a load
Load - the resistance that a lever is designed to move
