how can you reduce pressure while applying less force?give one application .
Answers
Answer:
Pressure is the force per unit area. The SI Unit of Pressure is the pascal (Pa). A pascal can be defined as a force of one newton applied over a surface area of one meter square. In other forms,
Pressure = Force / Area
The pressure is dependent on the area over which the force is acting, without any change in the force, the pressure can be increased and decreased. The Force applied to be constant if the surface becomes smaller the pressure increases and vice versa.
Some Practical Examples
Answer: By applying pascal's law
Explanation: we will decrease the pressure by keeping the force unchanged. We will increase the area of contact.More area,less pressure.
Example in case of a hammer.
The area is enlarged , so that when the screw is hit, the wall does not cracks.
So keeping in mind-
F=A where f is force and a is area
As the area increases force decreases.
