Question

Define force and pressure. What do you do to get maximum pressure with a minimum force? Name at least one appliance based on this principle.

Answer 1

Hint:Despite the fact that both are physics concepts, there can be a significant difference between force and pressure. To comprehend the distinction, we must first comprehend the term and its application.

Formula used:
\[P = \dfrac{F}{A}\]
Where, $P$=pressure, $F$=force and $A$= area.

Complete answer:
Definition of force: A force is an external agent capable of altering a body's condition of rest or motion. There is a magnitude and a direction to it.
Definition of pressure: The force applied perpendicular to an object's surface per unit area across which that force is spread is known as pressure. We know that \[P = \dfrac{F}{A}\]. Hence we can maximize pressure by minimizing the area since pressure is directly proportional to the acting force and inversely proportional to the area on which the force acts.

Some applications are listed below:
-Trucks have pairs of wheels that increase the surface area of the road, allowing them to apply less pressure.
-When the area of the straps on school bags is increased, pressure is reduced, and we can carry the bags more comfortably.

Additional information: Force is the result of two objects interacting and attempting to affect the state of the object. The pressure is the force exerted on an object in a perpendicular direction to the object's surface, resulting in the force spreading across a specific region. This could be likened to the difference between stress and pressure. Pressure is the physical force per unit area, whereas force is the push and pull action that results in a change of motion and direction. As a result, if a force is applied over a vast area, the resulting pressure is low, whereas if the same force is given to a tiny area, the resulting pressure is high.

Note: Pressure is the physical force per unit area, whereas force is the push and pull action that results in a change of motion and direction .Hence don’t get confused, just remember this line and understand it: if a force is applied over a vast area, the resulting pressure is low, whereas if the same force is given to a tiny area, the resulting pressure is high.
