This branch of law is comparatively of recent origin. It provides relief when a person may get physical injury not by an impact, by stick, bullet or sword but merely by a nervous shock through what he has seen or heard. As far back as 1888, the Judicial Committee of the Privy Council in Victorian

Definition of metrology is a “Science of measurement”. The most important parameter in metrology is the length. Metrology is divided into Industrial Metrology and Medical Metrology under consideration of its application and may be divided into metrology of length and Metrology of time under consideration of its quantity. Definition of Metrology is mainly concerned with

As we have discussed already, the torque of an engine crankshaft varies considerably throughout the working cycle, due to variations in the crank positions, the pressure in the cylinder and the inertia force on the piston and connecting rod. If the value of the crankshaft torque, the turning moment T is plotted against the crank

Steam is an important medium for producing mechanical energy. A steam power plant continuously converts the energy stored in fossil fuels (coal, oil and natural gas). Steam has the advantage that it can be raised from water which is available in abundance. The steam power stations are very much suitable where coal is available in

Res Ipsa Loquitur : As a general rule, it is for the plaintiff to prove that the defendant was negligent. The initial burden of making out at least a prima facie case of negligence as against the defendant lies heavily on the plaintiff, but once this onus is discharged, it will be for the defendant

Vapour compression refrigeration system uses a liquefiable vapour as the refrigerant. In this system, the refrigerant used alternatively undergoes a change of phase from vapour to liquid and liquid to vapour during the cycle. In this, the isentropic expansion of Carnot cycle is replaced by a throttling process, expansion in a valve or capillary tube.

Advantages of Stirling engines They can run directly on any available heat source, not just one produced by combustion, so they can run on heat from solar, geothermal, biological, nuclear sources or waste heat from industrial processes. A continuous combustion process can be used to supply heat, so most types of emissions can be reduced.

In this chapter, we shall discuss the static and dynamic force analysis of planar mechanisms in detail. In our studies of “Kinematics of Machinery“, we limited ourselves to consideration of the geometry of the motions and of the relationships between displacement and time. But the force required to produce those motions were not considered. In

The subject ‘Theory of Machines’, also known as ‘Mechanics of Machines’, comprises: (i) the study of the relative motion between the parts of a machine, and (ii) the study of the forces which act on those parts. It is understood that most mechanical engineering activities revolve around a mechanical system whose function depends on the

In an I.C engine, moving parts rub against each other causing frictional force. Due to the frictional force, heat is generated and the engine parts wear easily. Power is also lost due to friction. To reduce the power loss and also wear and tear of the moving parts, a foreign substance called lubricant is introduced
