Levers And Planes

Question 1

What is in the middle of a first class lever

Answer 1

The fulcrum

Question 2

What is in the middle of a second class lever

Answer 2

The load

Question 3

What is in the middle of a 3rd class lever

Answer 3

Effort

Question 4

Define fulcrum

Answer 4

The fixed point or axis of the lever. Where lever turns

Question 5

Define load

Answer 5

The weight or resistance that the lever is moving

Question 6

Define effort

Answer 6

The force applied to move the load

Question 7

Define mechanical advantage

Answer 7

The efficiency of a lever. If something has low MA it means the effort arm is shorter than its load arm but if it has a high MA the effort arm is longer than its load arm

Question 8

Equasion for mechanical advantage

Answer 8

Effort arm/load arm

Question 9

Define effort arm

Answer 9

Distance between effort and fulcrum

Question 10

Define load arm

Answer 10

Distance between load and fulcrum

Question 11

What plane does the sagittal axis go with

Answer 11

Frontal plane

Question 12

Which plane does the longitudinal axis go with

Answer 12

Transverse plane

Question 13

What plane does the transverse axis go with

Answer 13

Sagittal plane

Question 14

Whats the acronym to remember the planes and axisss

Answer 14

Some Footballers -Like To -Take Shots

Question 15

What movements does the sagittal plane allow

Answer 15

Flexion and extension e.g. sprinting

Question 16

What movements does the transverse plane allow

Answer 16

Rotational movements around the longitudinal axis e.g. 360 twist

Question 17

What movement does the frontal plane allow

Answer 17

Abduction and adduction e.g. cartwheel

Question 18

Define plane

Answer 18

An imaginary line that shows the direction of movement

Question 19

Define axis

Answer 19

An imaginary line through the body around which it rotates

Question 20

Where does the line pass in a transverse axis

Answer 20

Passes horizontally through the body e.g. like a table footballer

Question 21

Where does the line pass through in the longitudinal axis

Answer 21

Passes vertically through the body from top to bottom

Question 22

Where does the line pass through in a sagittal axis

Answer 22

Passes through the body from front to back
