Question

A force of 20 N acts on a smaller piston of a hydraulic press with an area of ​​10 dm2. How much force does the liquid act on a larger piston of 120 cm2?​

Answer 1

Force = 240 Newton

Step-by-step explanation:

Given the following data;

Force = 20 N

Area = 10 dm²

First of all, we would determine the pressure exerted by the hydraulic press on the small piston;

Conversion:

1 square decimeter = 0.01 square meters

10 square decimeters = 0.1 square meters

Mathematically, pressure is given by the formula;

Pressure = force/area

Substituting into the formula, we have;

Pressure = 20/0.1

Pressure = 200 N/m²

Next, we find the force acting on the larger piston using the same pressure;

Conversion:

100 centimeters = 1 meter

120 centimeters = 1.2 meters

Force = pressure * area

Force = 200 * 1.2

Force = 240 Newton
