what is the MA if R=F
- no advantage
what is MA if R < F
- disadvantage
what is MA if R > F
- advantage
what is the MA if FMA = RMA
- no advangtage
what is the MA if FMA < RMA
- disadvantage
what the MA if FMA > RMA
- advantage
what is at an advangtage when MA > 1
force
what is at and advantage when MA <1
speed and ROM
1st, 2nd, 3rd class levers
1st: R-A-F or F-A-R
2nd: F-R-A
3rd: A-F-R
what is the advantage of 2nd class levers
- MA will always be >1
what is the advantage of 3rd class levers
- MA will always be <1
what motion do levers act in
rotational
equation for MA
R/F OR FMA/RMA
