DnT- Hydraulic Systems

Question 1

First rule

Answer 1

If the input and output cylinders are the exact same size (and the system has been filled with hydraulic fluid) the input force = the output force and input piston travelled = output piston travelled
Input = Output

Question 2

Second rule

Answer 2

Difference in size = difference in MA
If the output cylinder is 2x bigger than the input cylinder then the MA of the output cylinder is 2x more than the input cylinder, which means Output force= 2x more than the Input force also Output force= 2x less distance than the Input force

Question 3

MA=

Answer 3

Load (output)/ effort (input)

Question 4

Control mechanisms

Answer 4

One way valve

Hydraulic jack

Question 5

One way valve

Answer 5

The input pushes fluid causing the output piston to rise and life the object.
The valve prevents fluid from back so that the object stays raised

Question 6

Hydraulic jack

Answer 6

Consists of two connected cylinders, big and small, where force is applied to the smaller cylinder that creates pressure in both cylinders.
Since the large cylinder has a larger area, the large cylinder produces a greater force
