Answer:
The input force needed is 225 Newtons
Step-by-step explanation:
From hydraulic pressure laws, we have that the pressure at the same level throughout the body of a fluid is equal.
This means that for the Hydraulic Jack, input pressure = output pressure
Recall,Pressure is a ratio of force and area
i.e pressure = Force / Area
For the hydraulic jack to work properly, the pressure at the input end must be equal to the pressure at the output end.
[tex]\frac{F_{1}}{A{1}} = \frac{F_{2}}{A_{2}}[/tex]
[tex]\frac{9000}{4}=\frac{Force}{0.1}[/tex]
From this we can compute that the Input force = 225 Newtons
Answer:
Step-by-step explanation:
Since the pipe is an enclosed container, we would apply Pascal's law which states that a pressure applied to a fluid in a closed container is transmitted equally to every point of the fluid and the walls of the container,
This means that pressure at input = pressure at output
Pressure = force /area
Input force = unknown
Input area = 0.1 m²
Output force = 9000N
Output area = 4m²
Therefore
Input force/0.1 = 9000/4
Input force = 0.1 × 9000 /4 = 225N
