Question

A hydraulic press has an input piston 10mm. in diameter and an output piston 50mm. in diameter. an input force of 80n gives an output force of [a] 400n [b] 3.2 n [c] 16n [d] 2000n

Answer 1

the output force will be option a i.e 400n

Answer 2

Concept introduction:

According to Pascal's law, regardless of the shape of the container, any force given to a confined fluid is transferred evenly in all directions throughout the fluid.

Explanation:

Given that, a hydraulic press has an input piston $10mm$. in diameter and an output piston $50mm$.

We have to find, the output force.

According to the question,

According to Pascal's law the pressure at two end of hydraulic press will be:

$F1/A1=F2/A2$

⇒$80/10=F2/50$

⇒$F2=400N$

Final Answer:

(a)$400N$
