Answer:
The force need to be applied on a 0.8 m² piston to lift the crate is 48 N.
Explanation:
Given that,
Force = 1500 N
Area [tex]A= 25 m^2[/tex]
We need to find the force to be applied on a 0.8 m2 piston to lift the crate
Using formula of pressure
The pressure is the force upon area.
[tex]P =\dfrac{F}{A}[/tex]
Where, F = force
A = area
Pressure for first force,
[tex]P =\dfrac{F}{A}[/tex]
[tex]P =\dfrac{1500}{25}[/tex]...(I)
Pressure for second force,
[tex]P =\dfrac{F}{0.8}[/tex]...(II)
Equate the equations (I) and (II)
[tex]\dfrac{1500}{25}=\dfrac{F}{0.8}[/tex]
[tex]F=\dfrac{1500\times0.8}{25}[/tex]
[tex]F=48\ N[/tex]
Hence, The force need to be applied on a 0.8 m² piston to lift the crate is 48 N.
