Answer 1

English Translation:

What is the force per unit area called?

(A) Friction (B) Pressure

Pressure is referred to as force per unit area.

the correct answer is option B.

• The force per unit area is called Pressure. The S.I. unit of pressure is Pascal (Pa).
• 1 Pascal is equal to 1N / m².

Formula :

P = F/A

In other words, A perpendicular force of 'F' Newton applied to a surface area of 'A' results in pressure exerted on the surface equal to the F/A ratio.

The different types of Pressure are

• Absolute Pressure
• Atmospheric Pressure
• Differential Pressure
• Gauge Pressure

An illustration would be that a sharp pin is simpler to hammer than a dull pin. This is due to the fact that a blunt pin's end has a lesser area than a sharp pin's end. As a result, there is an increase in pressure, which makes it simpler to hammer the sharp pin.
