Revised 2003.
This document discusses applications of fluid mechanics principles in engineering, including braking systems and lifting devices. It describes how Pascal's principle allows hydraulic braking systems and elevators to function. Anti-lock braking systems and tower cranes are presented as innovations utilizing hydraulics. Wing flap hydraulics are provided as an example of hydraulics in aeronautics. Key fluid mechanics concepts like Pascal's principle, pressure, and Archimedes' principle are defined.
The aim is to design and to develop an air brake system based on exhaust gas is called “fabrication of air brake system using engine exhaust gas”. The main aim of this project is to reduce the workloads of the engine drive to operate the air compressor, because here the compressor is not operated by the engine drive.
Here we are placing a turbine in the path of exhaust from the engine. The turbine e is connected to a dynamo by means of coupling, which is used to generate power. Depending upon the airflow the turbine will start rotating, and then the dynamo will also starts to rotate. A dynamo is a device which is used to convert the kinetic energy into electrical energy. The generated power can be stored in the battery and then this electric power has loaded to the D.C compressor. The air compressor compresses the atmospheric air and it stored in the air tank and the air tank has pressure relief valve to control the pressure in the tank . The air tank supplies the compressed pneumatic power to the pneumatic actuator through solenoid valve to apply brake. The pneumatic actuator is a double acting cylinder which converts hydraulic energy into linear moti on.
The team converted a gas-powered go-kart to electric power, designing mounts and testing performance. They benchmarked the gas kart, creating a mathematical model to predict the electric kart's performance. This helped select components like batteries and a motor. Fabricated mounts held the motor, batteries, and electronics. Final testing showed the electric kart met or exceeded the gas kart's performance.
This document discusses a power generating shock absorber that converts kinetic energy from vehicle suspension movement into electricity. It introduces the concept of a regenerative shock absorber and describes how a power generating shock absorber works using a linear motion electromagnetic system. The system includes a magnet stack, stator coil windings, and electronics to generate alternating current as the magnets move within the coils during suspension motion. This electricity can be stored in vehicle batteries to increase fuel efficiency. Benefits include recovering energy normally lost as heat and using it to power vehicle electrical systems.
This innovative technology helps in protection of vehicular accidents by using a shear thickening based smart fluid which can absorb impact forces, thus reducing the damage to critical components and people in a vehicle.

Innovative methods to save energy are needed with continued escalation in energy costs. One area is in automotive applications where the objective is to increase the efficiency in miles per gallon(mpg). Moving an average vehicle through still air at a velocity of 70 miles per hour(mph) requires from 30 to 80 horsepower depending on the design and size of the vehicle. This energy is wasted and not recoverable. One method to recover some of this energy is to utilize a fan or turbine to convert the moving air to electrical energy. Depending on the size of the fan and generator that is powered by the moving air, up to 1 to 2 horsepower could be generated at 70 mph. If the air driven generator could supply the vehicle’s electrical load at highway speeds, this would reduce the load to the gasoline driven engine thus increasing gas mileage. Average gas mileage could increase up to 5 mpg if a wind driven generator could supply the electrical energy to the vehicle at highway speeds. This project is to evaluate the feasibility of this concept. If proven by laboratory measurements, air driven generation of automotive electrical energy would have a significant impact on fuel usage. In addition, an engineering project of this type would result in patentable inventions and potential monetary benefit to MTSU. A successful program would lead to visibility for the University and increased student enrollment. These objectives are in line with the strategic goals of the University.

An engine stand is a tool used to hold large engines in midair during repair work. It allows mechanics easy access to all sides of the engine. While small engines can be laid on a table, large engines require support from their engine mounts. Engine stands are mounted on casters so the engine can be moved around the shop. They are often used with engine cranes to install or remove engines. The document then describes a budget-friendly way to create a simple engine stand using sawhorses and wood boards to support the engine at its mount points, allowing it to be rotated and stored out of the way when not in use.

This thesis explores optimising the design of small-scale standing wave thermoacoustic coolers and engines using a multi-objective approach. Mathematical models are developed to optimise geometric stack parameters for maximum performance. The optimisation problems are formulated as mixed-integer nonlinear programs with multiple objectives. A lexicographic method is used to compute the entire Pareto front and identify optimal solutions. Experimental results on 36 stacks show trends in agreement with models. The approach provides fast estimates of optimal stack geometry and position for small-scale thermoacoustic devices.
Abstract— A brake is a mechanical gadget which hinders movement. Its inverse part is a grasp. Vortex current brakes utilize attractive fields to change over motor vitality into electric current in the brake plate, blade, or rail, which is changed over into warmth. Brakes are by and large connected to turning axles or wheels, however may likewise take different structures, for example, the surface of a moving liquid (folds sent into water or air). Erosion brakes on autos store braking heat in the drum brake or circle brake while braking then direct it to the air step by step. When voyaging downhill a few vehicles can utilize their motors to brake.When the brake pedal of a present day vehicle with pressure driven brakes is pushed, at last a cylinder pushes the brake cushion against the brake plate which backs the wheel off. On the brake drum it is comparable as the chamber pushes the brake shoes against the drum which additionally backs the wheel off.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

PRINCIPLES OF FLUID MECHANICS
ARCHIMEDES PRINCIPLE
Archimedes principle explains buoyancy. If an object is placed in water and “weighted” it will register a
smaller value than if weighted in air. (Copeland, 2005) The upward force of the water partially balances
the weight force. The force exerted by the water on the object is the buoyancy force, and is dependent
on the density of the fluid and the volume of the submerged object. The buoyancy force is equal in value
to the weight of displaced fluid by the object.
Archimedes principle is used to calculate the specific gravity of objects.
The formula: Specific Gravity: weight of object in air
_______________________________
Weight loss when submerged in water
PASCAL’S PRINCIPLE
Pressure at the bottom of a container is greater than the top, and is independent of the shape of the
container. Pressure is also the same at all points at the same depth. Increasing pressure at the surface
with a piston, forcing it into the liquid will increase the pressure throughout the liquid.
This situation is known as Pascal’s principle and is stated as follows: Pressure applied to an enclosed liquid
is transmitted undiminished to every point in the fluid and to all the walls of the container. (Copeland,
2005)

HISTORY OF BRAKES
The early braking systems were used to stop vehicles with steel rimmed wheels. A curved block made out
of wood was manipulated against the wheel by leverage systems. The brake shoe was the normal way of
braking in a steam locomotive or a horse drawn vehicle.
External spoon brake
In 1895 the Michelin brothers replaced the steel rim with pneumatic rubber tyres. A new method was to
apply the force to the axle or to a drum on the axle. This was operated by the driver depressing a pedal.
The band and the drum had to be continuously replaced due to poor friction quality which led to a
replacement friction material. Herbert Frood processed an asbestos fabric in 1908 which was used as a
replacement.
The next development in 1902 was drum brakes by Louis Renault who designed an internal expanding
brake shoe. This design principle remained for the next 50 years.
Cams were used to force the shoes onto the drum with one having a pivot pin at the bottom to increase
the servo-assistance of the brakes. Equalising the brake pressure on both wheels was a problem

This was solved by the introduction of the hydraulic system, using fluid to transfer the force applied to the
brake pedal. One of the biggest developments of recent years has been the development of braking
systems that inhibit the tendance of a car to skid under braking. (Copeland, 2005)
The Anti-lock braking system works by using a sensor that detects the wheel when it begins to lock up, it
then releases the hydraulic pressure at the brake calliper to allow the wheel to spin again. The brake can
be reapplied and if the wheel locks again the process will be repeated.

PUBLIC TRANSPORT BRAKES
The rocket train design expanded rail transport as it offered speedier transport. Mechanical brakes were
difficult to use, in 1869 George Westinghouse developed an air brake that was held off by air pressure.
When air pressure was lost the brakes were applied which made it safer if the train lost air pressure.
Electric trains have an advantage as they can have regenerative braking systems. The application of the
brakes on a train results in the electric motor switching to an electric generator which generates
electricity to power other items in the train such as lights or air-conditioning.
REGENERATIVE BRAKING SYSTEM
When disc brakes are applied the energy is wasted. Physics tells us that energy cannot be destroyed, it
has to go somewhere with most dissipating as heat and is wasted. The braking systems on cars waste
energy and the driver can do nothing to stop this. Regenerative braking systems can recapture much of
the cars kinetic energy and convert it into electricity. These brakes are primarily found in hybrid vehicles.
Hybrid vehicles place a high degree of importance being able to keep the battery charged. Regenerative
brakes utilise the system that drives the vehicle to do the majority of the braking. When the brakes are
applied in an electric or hybrid vehicle the vehicles electric motor goes into reverse mode, causing it to
run backwards thus slowing the cars wheels. When the motor runs backwards it acts as an electric
generator, producing electricity that can be transferred to the vehicles batteries. This is best utilised in
city or stop start traffic when the brakes are used constantly. The vehicles momentum is used to get the
motor to run backwards as the mechanical energy puts the motor in reverse. Momentum is the property
that keeps the vehicle moving once it is up to speed. When the motor is reversed the electricity
generated by the motor is fed back into the batteries where it can be used to accelerate the vehicle again.
Electronic control in a regenerative braking system allows the driver to select certain presets that
determine how the vehicle will apply the brakes and when. Regenerative brake controllers are electronic
devices that control brakes remotely, deciding when the braking starts, ends and how quickly the brakes

need to be applied.
The brake controller may decide if motor capability is capable of handling the force necessary to stop the
car. If it is not capable it will turn the braking to the friction brakes averting a catastrophe.
The efficiency of regenerative braking system is the reason it has been developed. Conventional cars
efficiency is 20%, with the remaining 80% of its energy being converted to heat through friction.
Regenerative braking could capture as much as half that wasted energy and put it back to work.

IMPACT OF HYDRAULIC LIFTING DEVICES
Hydraulic systems have the following advantages over power systems.
• Equal forces are applied to each output cylinder
• Higher efficiency than other systems
• Less maintenance and more reliability
• Low inertia of moving parts allows hydraulic systems to start and stop quickly. (Rochford, 2011)
Hydraulic lifting devices contribute to safety in the workforce by reducing the human effort required to
raise materials or supply a safe working platform. Hydraulic lifting devices greatly reduce the chance of
back injuries in construction workers.
Hydraulic elevators are used in low-rise building up to 5 storeys. The elevator is pushed up the shaft by
hydraulically controlled pistons or a telescopic piston to save space. The advantage of this system is it
does not need overhead mounted equipment to lift the elevator. The pump can be located away from
the shaft and installation and running costs are less than an electric elevator.
Specialised work platforms that are hydraulically operated can lift workers up to heights quickly with
minimum effort. They allow workers to move freely and work safely while high off the ground.

RECENT INNOVATIONS
Hydraulic Jack
The hydraulic jack forces compressible fluid into a cylinder by a plunger. Oil is used because it is a stable
fluid and is self- lubricating which minimises maintenance.
A Scottish machinist named Richard Dudjeon invented the hydraulic jack. Hydraulic cylinders have not
changed much over the years. The tolerances of the parts are tighter and the jack is still the hard working
push-pull tools they have always been.
Hydraulic jacks are easy to use, portable and lift loads from 1.5 to 3 tonnes. Hydraulic jacks have different
functions. Floor jacks are used to lift loads from the floor and in small areas bottle jacks are used. Ram
jacks have long arms and are used in the construction industry.
Jacks are utilised to make lifting and high pressure moving easy for industries. Hydraulic jacks are used by
service stations, storage establishments, automotive industries for a range of high pressure and heavy
duty lifting procedures.
The significance of jacks is that they make lifting and moving items or equipment easy for industries. The
hydraulic jack is easy to use and the process is accomplished quickly.

AERO INDUSTRY
Hydraulic systems in aircraft have multiple uses depending on the aircraft. Hydraulics is used to operate
wheel brakes, landing gear and some constant speed propellers in small aircraft. Larger planes utilise
hydraulics for flight control surfaces, spoilers, wing flaps and other systems.
The hydraulic system compromises a reservoir, pump, filter, selector valve to control the direction of the
flow, relief valve and an actuator.
The fluid is pumped to an actuator. An actuator is a cylinder with a piston inside that converts fluid power
into work which creates the power needed to move an aircraft system. Cylinders can be single or double
acting depending on the systems requirements. A selector valve allows the control of the fluid direction.
This system operates the extension and retraction of the landing gear during which the fluid needs to
work in different directions. If the pressure within the system is excessive the relief valve provides an
outlet to reduce fluid pressure.
The hydraulic fluid most widely used for aircraft has a mineral base. This fluid, a kerosene-like petroleum
product has good lubricating properties. The fluid has additives to inhibit foaming and prevents the
formation of corrosion. The fluid is chemically stable and changes viscosity very little with temperature
and is dyed for identification.

An example of a double acting cylinder
The gland is screwed into one end of the cylinder and the rod passes through it, a pressure seal and wiper
seal are fitted to the gland to resist oil pressure and clean rod when it is moving in and out of the cylinder.
