Pressure is a magnitude of a force which exerts on a body per area unit of a pressing plane.Pressure consist of : Pressure on Solid
Pressure on LiquidPressure on Gas
Pressure

Example Problem Pressure on Solid1. A box which has weight 500 N and base
area 1 m2 puts on the floor. Calculate the pressure that is given by the box to the floor.
2. Which block that have the biggest pressure? Block A that have weight 9 kg and base area 3 m2, or block B that have weight 3 kg and have base area 1 m2
3. Amir puts a wooden block with pad that touch floor with size 20 cm x 80 cm. If the pressure of that wooden block to the floor is 2,000 N/m2, calculate the force of the wooden block.
