Term
|
Definition
| A group of two or more gears |
|
|
Term
mutliplying gears
Which gear turns the most number of times?
Does the driven gear move faster or slower?
Does this change the turning direction? |
|
Definition
follower
faster
Yes they are turning opposite directions |
|
|
Term
Reducing Gears:
Which gear turns the most number of times?
Does the driven gear move faster or slower?
Does this change the turning direction? |
|
Definition
driver
Driven is slower
They are both turning opposite directions |
|
|
Term
Parallel Gears:
Which gear turns the most number of times?
Does the driven gear move faster or slower?
Does this change the turning direction? |
|
Definition
they turn the same amount of times
They turn at the same speed
They all turn opposite. |

Term
| MA for sprockets and gears |
|
Definition
| Speed Ratio= Number of driver gear teeth / Number of follower gear teeth |
|
|
Term
| Give an example of a MA that would be a force advantage and one that would be a speed advantage. |
|
Definition
Force - 1< (more than one)
Speed - 1> (less than one) |

Term
| A class two lever is like a wheel and axle where the load is attached where? |
|
Definition
[image]Class 3 -> load attached to the wheel[image] Speed Advantage (Effort force distance is less than load distance this requires more fore but less distance.)
[image] Class 2 -> load attached to axle[image] Force advantage (effort froce distance is more than the load distance which makes the job easier (use less force)) |
