hydraulics Flashcards
1
Q
what r and when used
A
use water (pneumatic use air + gas)
for applications that need higher force and heavy lifting
pn for low scale engineering and mechanical tasks
2
Q
adv of hydraulic
A
- easy to control + accurate
- simpler and easier to maintain
- deliver constant force regardless of speed changes
- easy to spot leagues of hydraulic systems
- higher braking power
3
Q
pressure
A
cont, physical force exerted on object by something in contact with it
- force/area
4
Q
pascals principle
A
in a fluid at rest in closed contained, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the containers
