When someone uses his thumb to push a pin into a block of wood the pressure on the wood is greater than the pressure on this thumb because the area of the pin on the thumb side is larger than the area of the pin on the wood side
What is pressure?
The total applied force per unit of area is known as the pressure.
The pressure depends both on externally applied force as well the area on which it is applied.
The mathematical expression for the pressure
Pressure = Force /Area
the pressure is expressed by the unit pascal or N /m²
Since, the area of the pin on the thumb side is larger than the area of the pin on the wood side, when someone uses his thumb to push a pin into a block of wood, the pressure on the wood is greater than the pressure on this thumb.
