Question 7

Give an example of a first class lever in the body

Answer 7

In the neck

e.g. when heading a ball

Question 8

Give an example of a second class lever in the body

Answer 8

In the ankle area

e.g. standing on tiptoes

Question 9

Give an example of a third class lever in the body

Answer 9

In the elbow

e.g. performing a bicep curl

Question 10

Describe a first class lever

Answer 10

A lever where the fulcrum is located in the middle

Question 11

Describe a second class lever

Answer 11

A lever where the load is located in the middle

Question 12

Describe a third class lever

Answer 12

A lever where the effort is located in the middle

Question 13

What factors affect mechanical advantage?

Answer 13

The length of the effort arm compared to the load (resistance) arm

Question 14

What classes of lever can operate at a mechanical disadvantage?

Answer 14

First and third

Question 15

What classes of lever can operate at a mechanical advantage?

Answer 15

First and second

Question 16

Explain the term “mechanical disadvantage”

Answer 16

A lever in which the effort arm is shorter than the load arm, operates at a mechanical disadvantage. This means that a large effort is required to lift a relatively small load, however, this means that the lever can move quickly with a large range of movement,

Question 17

Explain the term “mechanical advantage”

Answer 17

A lever in which the effort arm is longer than the load arm, operates at a mechanical advantage. This means that a small effort is required to lift a relatively large load, however, the range of movement is relatively low.
