The document defines and describes the various types of brake systems used in automobiles. It discusses mechanical, disc, hydraulic, power-assisted, air, and hand brake systems. The hydraulic brake system is the most common, using fluid pressure to slow wheels. When the brake pedal is pressed, fluid pushes brake pads against a disc or drum, converting kinetic energy to heat and slowing the vehicle. Master cylinders control fluid pressure to wheel cylinders for balanced braking on all wheels. Power-assisted and air brakes use vacuum or compressed air to augment braking force. Hand brakes provide independent parking capability.
“An object remains in its state of rest or in motion until and unless acted upon by an external force” Newton’s first law of motion, this law by Sir Isaac Newton gave rise to the development of braking system in an automobile, developing an automobile vehicle not only requires the power source but also the efficient braking system as higher the horse power higher will be the brake force required to stop or de accelerate that vehicle. This thought gave rise to many researches in the field of braking and results in its evolution due to which today we have flexibility in choosing a suitable braking system according to our need. So let’s just start our article with the curiosity about the various types of braking system.
In an automobile vehicle, a braking system is an arrangement of various linkages and components (brake lines or mechanical linkages, brake drum or brake disc , master cylinder or fulcrums etc) that are arranged in such a fashion that it converts the vehicle’s kinetic energy into the heat energy which in turn stops or de accelerate the vehicle.
The conversion of kinetic energy into heat energy is a function of frictional force generated by the frictional contact between brake shoes and moving drum or disc of a braking system.
With ABS system, the driver can brake hard, take the evasive action and still be in control of the vehicle in any road condition at any speed and under any load.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop.

2. DEFINITION O F BRAKE SYSTEM:
A brake is one of the most important controls of
the vehicle.
This is a combination of some interactive parts.
It absorbs energy from the moving part and
slows down the vehicle with the help of
friction.
3. FUNC TIONS OF BRAKE SYSTEM:
The function of the brake system is to stop
the vehicle within the smallest possible distance
and hence this is done converting the kinetic
energy of the vehicle into the heat energy which
is dissipated into the atmosphere.
4. TYPES OF BRAKE SYSTEM IN
AUTOMOBILE:
The brake system in an automobile can be
classified into these following categories:
1. Mechanical Brake
2. Disc Brake
3. Hydraulic Brake
4. Power-assisted Brake
5. Air Brake
6. Electric and
7. Hand brake System
5. ME C HANIC AL BRAKE:
The mechanical
brake is used in
small power
automobiles like
scooters, motorcycles
and some modern
vehicles.
6. As the brake pedal is pressed cam
rotates, which pushes the brake
shoes outwards and hence brake
lining provided on the outer surface
of the shoes rub against rotating
the drum and hence slow down or
stops the vehicles because the
drum is connected to the wheels.
As the pedal is released, due to
retracting spring force shoes return
to its original position.
7. DIS C BRAKE:
The disc brake is used in motor vehicles and cars,
etc.
When the pedal is pressed piston pushes the pad
by the pressure of the hydraulic fluid. The
diagram is shown below:
8. The friction pad rub against the rotating disc
connected to the wheels of the vehicle and thus
braking takes place.
And as the pedal is released friction pad returns
to its original position between the pressure of
hydraulic fluid reduces.
9. HYDRAULIC BRAKE:
Hydraulic brake works on the principle which
is based on Pascal’s principle, which states that
“confined liquid transmits pressure without loss
in all direction”.
This is simple in construction and has an equal
braking effort to all wheels and smooth
operation.
10. When the brake pedal is pressed, fluid from the
master cylinder enters into the wheel cylinders
through pipelines by the force of the piston.
Due to the liquid force, the piston of the wheel
cylinder pushes outward which pushes the shoes
outward.
Lining rub against the drum and hence braking
take place.
Now when the pedal is released, the piston of the
master cylinder moves backward and fluid from
the wheel cylinder moves to the master cylinder
through the check valve.
This type is commonly used in all cars, etc.
11. MASTER CYLINDER:
The master cylinder is the heart of the
hydraulic brake system.
● It consists of two chambers:
The reservoir.
Compression chamber, in which piston reciprocates.
The piston is connected to the brake pedal
through the piston rod. From the reservoir, fluid
enters the compression chamber through the
parts as shown.
The master cylinder is connected to the wheel
cylinders through the pipe.
12. The check valve is provided in order to give
passage for entering fluid from the wheel cylinder
to the master cylinder when the pedal is released.
14. POWER-ASSISTED OR VAC UUM BRAKE:
The line diagram indicates the construction of a
power-assisted or vacuum brake as shown below.
15. As the brake pedal is pressed, the fluid pressure
causes the upper valve of a control unit to open
and lower the valve to close.
Thus left the side of the servo cylinder piston is
exposed to atmosphere and vacuum acts on the
right side, which causes the braking effort.
Braking takes place by suction from the engine
inlet manifold.
16. AIR BRAKE:
This type of air brake system is commonly used
in heavy vehicles such as buses, trucks, etc.
In this also when the brake pedal is pressed, air
to atmosphere enters the compressor through the
air filter to the reservoir through unloader value.
17. From unloader valve air enter brake chamber
brake valve.
Brake valve is fitted in order to control the
intensity of braking. Thus braking takes place.
When the pedal is pressed shoes return to its
original through position through the spring
force.
18. GIRLING MECHANISM BRAKE:
This system consists of an expander used for
braking and adjuster unit to adjust the brake
shoes when desired.
As the brake pedal is pressed, the pulls rod of
expander pulled out which pulls out the conical
wedge.
The brake shoe connected to the conical wedge
through plunger and steel roller ball pulls
outward. Thus braking the wheel.
19. When the pedal is released, spring force brings
the brake shoe to its original position.
It requires less friction,. Without jacking up
vehicles brakes can be adjusted.
20. ELECTRICAL BRAKE SYSTEM:
The principle of working of this type of brake is to
utilize the electromagnetic force on the brake
shoes.
It consists of an electromagnet, armature disc.
An electromagnet is mounted on the backplate
and armature disc is fed to the drum.
This is simple in construction.
For working, electric current for the battery is
utilized to energize the electromagnet which
actuated the cams that expands the shoes. Thus
braking the wheel.
21. HAND BRAKE SYSTEM:
Hand brakes or the parking brakes operate
independently of the foot brakes.
These are used for parking on slopes or while
waiting at traffic lights, where the handbrake
function is mainly to minimize accidents.
This brake is applied after the foot brake is
applied.
These are mechanical brakes.
Apart from the hydraulic braking system, all cars
have a mechanical handbrake acting on two
wheels – usually the rear ones.
22. The handbrake gives limited
braking if the hydraulic system
fails completely, but its main
purpose is as a parking brake.
The handbrake lever pulls a
cable or pair of cables linked to
the brakes by a set of smaller
levers, pulleys, and guides whose
details vary greatly from car to
car.
A ratchet on the handbrake lever
keeps the brake on once it is
applied. A push-button
disengages the ratchet and frees
the lever.
On drum brakes, the handbrake
system presses the brake linings
against the drums.
23. have
Disc brakes sometimes
handbrake arrangement,
a comparable
but because it is
difficult to place the linkages on a compact
caliper, there may be a completely separate set of
handbrake pads for each disc.
