Calculation of Pressure

To calculate the pressure exerted by a force on a given area, we need to use the formula:

Pressure = Force / Area

Given:
Force = 30 N
Area = 120 cm²

Conversion of Area
The given area is in square centimeters (cm²). However, it is easier to work with the SI unit of area, which is square meters (m²). Therefore, we need to convert the area from cm² to m².

1 m² = 10,000 cm²

120 cm² = 120 / 10,000 m²
= 0.012 m²

Therefore, the area in square meters is 0.012 m².

Substituting Values into the Formula
Now, we can substitute the given values into the formula to calculate the pressure.

Pressure = 30 N / 0.012 m²
= 2500 N/m²

Interpretation
The pressure exerted when a force of 30 N is applied to an area of 120 cm² is 2500 N/m².

This means that for every square meter of the given area, there is a pressure of 2500 newtons. Pressure is defined as the force applied per unit area, so in this case, the force of 30 N is spread over an area of 0.012 m², resulting in a pressure of 2500 N/m².

The pressure exerted by a force on an object or surface is important in various fields, such as engineering, physics, and even everyday life. Understanding pressure helps us analyze and design structures, calculate the effects of forces on different materials, and make informed decisions in practical situations.
