Where is the load in a second class lever?

The load sits between the fulcrum and the effort. A wheelbarrow works as a second class lever.

Where is the effort in a third class lever?

The effort sits between the fulcrum and the load. Most levers in the body are third class.

How does the memory aid FLE 1, 2, 3 help identify a lever class?

FLE names the part that sits in the middle of each class. The fulcrum is central in first class, the load in second and the effort in third.

Describe how a linear diagram of a second class lever is laid out.

A straight bar has the fulcrum at one end and the effort at the other end. The load sits on the bar between them.

Questions from this subtopic

Each one with the model answer underneath.

1
What are the three parts of a lever system, and what provides each one in the body?
Model answer
A lever system has a fulcrum, an effort and a load, also called the resistance. In the body the joint is the fulcrum and the muscle supplies the effort. The load is the weight of the body part plus anything it moves.
2
Where is the fulcrum in a first class lever?
Model answer
The fulcrum sits between the effort and the load. A seesaw is an everyday first class lever.
3
Where is the load in a second class lever?
Model answer
The load sits between the fulcrum and the effort. A wheelbarrow works as a second class lever.
4
Where is the effort in a third class lever?
Model answer
The effort sits between the fulcrum and the load. Most levers in the body are third class.
5
How does the memory aid FLE 1, 2, 3 help identify a lever class?
Model answer
FLE names the part that sits in the middle of each class. The fulcrum is central in first class, the load in second and the effort in third.

Describe how a linear diagram of a second class lever is laid out.
Model answer
A straight bar has the fulcrum at one end and the effort at the other end. The load sits on the bar between them.

AThe aerobic training zone of a 20-year-old is 120–160 bpm.

BMaximum heart rate = 220 − 20 = 200 bpm.

CThe zone runs from 0.6 × 200 = 120 bpm to 0.8 × 200 = 160 bpm.
