Q

mechanical advantages

A

to move a load faster than it is possible without a lever

to move a heavier load with less force than without a lever

F,L,E

17
Q

2nd class advantage

A

provides the force to lift heavy loads

18
Q

2nd class disadvantage

A

a small range of movement and can’t move quickly

19
Q

why does the 2nd class have these advantages and disadvantages

A

due to the load being closer to the fulcrum than the effort

20
Q

3rd class advantage

A

provides speed and wide range of movement

21
Q

3rd class disadvantage

A

the greater force required than the load to be moved

22
Q

why does 3rd class have these advantages and disadvantages

A

due to the effort being closer to the fulcrum than the load

23
Q

three types of plane

A

sagittal, frontal, transverse

24
Q

three-axis of movement

A

sagittal, frontal, vertical

25
Q

what planes and axis go together

A

sagittal plane and frontal axis
frontal plane and sagittal axis
transverse plane and vertical axis

26
Q

example of the sagittal plane and frontal axis

A

front somersault

27
Q

examples of the frontal plane and sagittal axis

28
Q

example of the transverse plane and vertical axis

A

full twist

29
Q

movement on a sagittal plane and frontal axis

A

flexion and extension

30
Q

movement on frontal plane and sagittal axis

A

abduction and adduction

31
Q

movement on transverse plane and vertical axis

A

rotation and twisting
