Mechanical advantage Flashcards
1
Q
How much a lever can increase speed depends on
A
the lengths of resistance arm and effort arm
2
Q
Resistance arm =
A
distance between fulcrum and load
3
Q
Effort arm =
A
distance between fulcrum and effort
4
Q
The longer the resistance arm…
A
the greater speed can be generated
5
Q
the longer the effort arm…
A
the more force can be generated
6
Q
Which class lever system generated most speed
A
third class lever system as load and fulcrum are furthest apart
7
Q
Which class lever system generated most force
A
second class lever system as effort and fulcrum are furthest apart
8
Q
How can you increase the length of the effort arm
A
Bats, racquets and equipment
9
Q
Mechanical advantage =
A
Effort arm/Resistance arm
