The term introduction of robot means different things to different people. Science fiction books and movies have strongly influenced what many people expect a robot to be or what it can do. Sadly the practice of robotics is far behind this popular conception. One thing is certain though robotics will be an important technology in

A Diesel power plant (also known as Stand by diesel power station) uses a diesel engine as prime mover for the generation of electrical energy. This power station is generally compact and thus can be located where it is actually required. This kind of power station can be used to produce limited amounts of electrical

In these high energy rate forming processes large amount of energy is applied for a very short interval of time. Many metals tend to deform more readily under extra fast application of load which make these processes useful to form large size parts out of most metals including those which are otherwise difficult to form.

To deform the metal permanently, the stress must exceed the elastic limit. At room temperature, the metal is in a more rigid state than when at higher temperature. Hot Working and Cold Working Metal Forming. Thus, to deform the metal greater pressures are needed when it is in cold state than when in hot state

A boiler which generates steam at pressure greater than 80bar, a temperature of about 500°C, producing, steam more than 250 tons per hour called high pressure boilers. By using high pressure boilers, low grade fuels can be burned easily. High pressure boilers are water tube boilers and use pulverized coal firing. Examples of these boilers

In Hydro electric power plants the energy of water is utilized to move the turbine which intern run the electric generators. Hydraulic energy is converted into Mechanical energy by the turbines, when coupled with generator produces the power. Features of Hydro electric power plants: Large investments Long gestation period Increased cost of power transmission Hydro

Static Balancing A system of rotating masses is said to be in static balance if the combined mass centre of the system lies on the axis of rotation, static vs dynamic balancing. Condition for static balancing : The net dynamic force acting on the shaft is equal to zero. In other words, the centre of

A machine has many moving parts. Some machines have balancing of rotating masses motion and some of them have reciprocating motion. If these moving parts are not in complete balance, inertia forces are set up which may cause excessive noise, vibration, wear and tear of the system. Thus, balancing is the process of designing or
