Gears and hydraulics Flashcards
1
Q
Larger gears will have
A
1) A larger moment - high turning effect
2) Turn slower
2
Q
Smaller gears will have
A
1) A smaller moment - low turning effect
2) Turn quicker
3
Q
The distance moved by each gear will be the same so:
A
COG 1 no of teeth x turns = COG 2 no of teeth x turns
4
Q
In a sealed container what is the water pressure
A
Equal in all directions
5
Q
Hydraulics use ______ to transmit _________ between pistons
A
Hydraulics use liquids to transmit force between pistons
6
Q
What can they be used todo
A
They can magnify force so the effort on one piston can be magnified to move a heavier load with the other piston
7

What is pressure?
A
Force / area
8
Q
