Question

Draw an example of the three classes of levers and label the Load, Effort, and Fulcrum

Answer 1

Sure! Here is an example of the three classes of levers:

1. First Class Lever:
- Load: Weight being lifted (e.g. book)
- Effort: Force applied to lift the weight (e.g. hand)
- Fulcrum: Point where the lever pivots (e.g. tabletop)

2. Second Class Lever:
- Load: Weight being lifted (e.g. wheelbarrow with a load)
- Effort: Force applied to lift the weight (e.g. hands pushing down on the handles)
- Fulcrum: Point where the lever pivots (e.g. wheel axle)

3. Third Class Lever:
- Load: Weight being lifted (e.g. forearm lifting a dumbbell)
- Effort: Force applied to lift the weight (e.g. bicep muscle contracting)
- Fulcrum: Point where the lever pivots (e.g. elbow joint)
