                                     A pressure switch turns an electric circuit on or off at a preset pressure. This pressure is referred to as the set point of the switch. A bourdon tube, a diaphragm, or a bellows can actuate the switch .                              Pressure Switch working:-                                The contacts in a pressure switch may be normally open or normally closed if the pressure is below the set point.  The contacts in a normally open (N.O) switch remain open until the pressure increases above the set point. Then the sensing element makes the contact snap to the closed position. The contacts open again when the pressure decreases below the set point.  The contacts in a normally closed (N.C) switch remain closed until the pressure increases above the set point. Then the contact snaps open and remain open until the pressure decreases below the set point position. Most pressure switches contains two sets of contacts. One normally o

              The most important factors in tire of car and other vehicle is tire inflated pressure properly. Here is the Question. In which condition we say that the tire is properly inflated? In the below picture the 2nd one (center) tire is properly inflated beside others.             Proper tire inflation pressure improves fuel economy, reduces braking distance, improves handling, and increases tire life, while under inflation creates overheating and can lead to accidents. Approximately ¾ of all automobiles operate with at least one under-inflated tire. The main causes of under inflation are natural leakage, temperature changes, and road hazards. Drivers typically do not check tire pressure unless they notice unusual vehicle performance. Visual checks are often insufficient to determine under inflation. History:-              In 2000, the U.S. Transportation Recall Enhancement, Accountability, and Documentation Act (TREAD) requested that the National Highwa

Radial engine:-                    The radial engine is an internal combustion engine configuration in which the cylinders point outward from a central crankshaft like the spokes on a wheel. This configuration was very commonly used in aircraft engines before being superseded by turbo-shaft and turbojet engines. It is a reciprocating engine.                                         Although not that used nowadays radial engine is a cute little engine that was in the beginning of the aerospace transportation. It was very helpful and mainly used because of its small weight and size. That makes it comfortable and suitable for any machine that is close of space. Despite of its small size and weight it does not make it less powerful than other engines. The same way the in-line engines are more powerful with more cylinders it is or powerful with more rows of cylinders. It was also comfortable for the World War II airplanes when the engine was in its peak. When it is war you need

Brake System Concept Mechanical brakes all act by generating frictional forces as two surfaces rub against each other. The stopping Power or capacity of a brake depends largely on the surface area of frictional surfaces as well as on the actuation force applied. The friction and wear encountered by the working surfaces are severe. Thus, the durability of a brake or service life between maintenance depends heavily on the type of material used to line the shoe or pad.                     Mechanical brakes are assemblies consisting of mechanical elements for the stopping of shafts in equipment drives. They use levers or linkages to transmit force from one point to another.  Ø       There are several types of mechanical brakes.            ü       Band brake ü       Drum brake ü       Disc brake ü       Cone brake Application Ø       Band brake  Band brake mostly used in bicycle.

Mechanical Mechanical engineering is the discipline that applies the principles of engineering, physics, and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery.It is one of the oldest and broadest field of the engineering disciplines.
