A chapati maker is a machine which converts balls of dough into chapatis. What effect of force comes into play in this process?

Pressure is defined as the force acting per unit area.


Note that the pressure is inversely proportional to the area. So smaller the area, larger the pressure on a surface.


Chapatti maker works on this principal. This large pressure converts balls of dough into chapattis.
