Movement Analysis

Question 1

How is a fulcrum represented on a diagram

Answer 1

A triangle

Question 2

How is effort represented on a diagram

Answer 2

An arrow in the direction the effort is applied

Question 3

How is the load (resistance) represented on a diagram

Answer 3

As a square

Question 4

How is a lever represented on a diagram

Answer 4

Straight Line

Question 5

What factors affects a lever’s type of mechanical advantage?

Answer 5

Distance between resistance and fulcrum

Distance between effort and fulcrum

Question 6

In the elbow’s third-class lever, how long is the resistance arm?

Answer 6

Very Long

Question 7

What is the effort in a second-class ankle lever?

Answer 7

The Gastrocnemius

Question 8

For which activities is a second-class lever ideal?

Answer 8

Lifting Weights

Question 9

What is mechanical advantage

Answer 9

Efficiency of a working class lever, calculated by effort/weight arm.

Question 10

Identify the lever system when kicking a ball

Answer 10

Third class lever

Question 11

Explain the mechanical advantage of the lever system at the ball of the foot in a sprint start.

Answer 11

This is a 2nd class lever, this means there will be a long effort arm compared to the resistance arm, therefore a small amount of effort is needed by the sprinter’s muscles to move her weight to allow her to accelerate.
