Answer:
6 m²
Explanation:
application of fluid pressure according to Pascal's principle for the two pistons is given as:
Where P₁ is the pressure at the input and P₂ is the pressure at the output.
But P₁ = F₁ / A₁ and P₂ = F₂ / A₂
Where F₁ and F₂ are the forces applied at the input and output respectively and A₁ and A₂ are the area of the input pipe and output pipe respectively
Since,
But A₁ = 0.2 m², F₁ = 250 N, F₂ = 7500 N. Substituting values to get:
Therefore, the area of the pipe below the load is 6 m²
