Design And Technology- Hydraulics

Question 1

First rule

Answer 1

If the INPUT and OUTPUT cylinder are the exact same size (and the system has been filled with hydraulic fluid) then the input force will be equals to the output force, and the input piston travelled would be equal to the 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 2d more than the input cylinder which means, the output force = 2x more than the input force also, the output force = 2x less than the input force.

Question 3

MA=

Answer 3

Load(output)/effort(input)

Question 4

Control mechanisms

Answer 4

One way valve and hydraulic Jack

Question 5

One way valve

Answer 5

The input pushes the fluid causing the output to rise and lift the object. The value prevents fluid from flowing back so that the object stays raised.

Question 6

Hydraulic Jack

Answer 6

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