Hi guys. In this post I'm going to tell you about the braking system in cars. If you know it already it just awesome. But he is for those who don't know and curious about it. The braking system of cars, buses etc also works on the basis of one law that is Pascal law. First we must know what is pascals law?
Definition:
" Pressure applied at any point of a liquid enclosed in a container is transmitted without loss to all other parts of the liquid."
Explanation:
An external force applied on the surface of a liquid increases the liquid pressure at the surface of the liquid. This increase in liquid pressure at the surface of the liquid this increase in liquid pressure is transmitted equally in all directions and to the walls of the container in which it is filled. This result is called pascal's law.
It can be demonstrated with the help of a glass vessel having holes all over the surface as shown in the picture. Fill it with water. Push the piston. The water rushes out of the holes in the vessel with the same pressure. The force applied on the piston exerts pressure on water. This pressure is transmitted equally throughout the liquid in all directions. In general this law holds good for fluids. Both for liquid and gasses.



In the picture you can see. The hydraulic brakes as shown in the picture allow equal pressure to be transmitted throughout the liquid. When the brake pedal is pushed, it exerts the force on the master cylinder which increases the liquid pressure in it . The liquid pressure is transmitted equally throughout the liquid in the metal pipes to all the piston of the other cylinders . Due to the increase in liquid pressure the piston on the cylinders move outward pressing the brake pads with the brake drums the force of friction between the brake pads and the brake drums stops the wheels completely.
