Q

What is mechanical advantage?

A

When the output of a lever is greater than the input - when the load is greater than the effort so you are getting more than you are putting in

16
Q

What is mechanical disadvantage?

A

When the effort and load are both on the same side of the fulcrum - the input is greater than the output

17
Q

What are the advantages of first class levers?

A

Stable
Strong
Increasing length increases mechanical advantage

18
Q

What are the disadvantages of first class levers?

A

Slow
Limited flexibility

19
Q

What are the advantages of second class levers?

A

Stable
Strong
Increasing the length increases mechanical advantage

20
Q

What are the disadvantages of second class levers?

A

Slow
Limited flexibility

21
Q

What are the advantages of third class levers?

A

Fast movement
Large range of motion
Increasing the length decreases mechanical advantage

22
Q

What are the disadvantages of third class levers?

A

The force applied (effort) must always exceed the load

23
Q

What is the sagittal plane?

A

An imaginary line dividing the body vertically into left and right sides

24
Q

What is the frontal plane?

A

An imaginary line dividing the body vertically from front to back

25
Q

What is the transverse plane?

A

An imaginary line dividing the body horizontally from top to bottom

26
Q

What is a sagittal axis?

A

An imaginary line that runs through to body from front to back

27
Q

What is the frontal axis?

A

An imaginary line that runs through the body from left to right

28
Q

What is the vertical axis?

A

An imaginary line that runs through to body from top to bottom

29
Q

What plane and axis does flexion/extension use?

A

Sagittal plane
Frontal axis

30
Q

What plane and axis does abduction/adduction use?

A

Frontal plane
Sagittal axis
