hydraulics

Question 1

what r and when used

Answer 1

use water (pneumatic use air + gas)
for applications that need higher force and heavy lifting
pn for low scale engineering and mechanical tasks

Question 2

adv of hydraulic

Answer 2

• 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

Question 3

pressure

Answer 3

cont, physical force exerted on object by something in contact with it
- force/area

Question 4

pascals principle

Answer 4

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
