Question

The radius of the press cylinder in a hydraulic press is equal to the diameter of its pump cylinder. Its mechanical advantage is __________.

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

let, the radius of the press cylinder $=R$

according to question radius of

pump cylinder $=R/2$

from, pascal's law pressure always Remaining

same in this system.

let, force exerted $=F_2$

force applied $=F_1$

$P_1=P_2$

Or $F_1\times \pi R^2=F_2\times \frac{\pi R^2}{4}$

or $\frac{F_2}{F_1}=4$

Answer : option $\left(D\right)$
