Forging Process
Forging process is perhaps the oldest metal working process and was known even during prehistoric days when metallic tools were made by heating and hammering. Forging is basically involves plastic deformation of material between two dies to achieve desired configuration. Depending upon complexity of the part forging is carried out as open die forging and closed die…

Fluid Mechanics and Its Properties
Fluid mechanics is a branch of science, which deals with the fluids behavior in the rest position and in the motion too. The study of science deals with the kinematics, dynamics and statists. The fluids at the rest position are known as fluid statics. If the fluid is in motion without considering the pressure forces then it…

Gas Laws
Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume.The following are the some of the important gas laws: § Boyle’s Law § Charles Law § Gay-Lussac’s Law § Avogadro’s law § Universal Gas Law Boyle’s Law: Boyle’s law states that the volume of a given mass of gas (V) is inversely proportional to its absolute pressure (P), provided the…

Hydro Electric Power Plant Turbine Advantages
To the power plant water source is regularly available without break. To generate electricity fuel is not required. It is properly termed as white coal. Through the turbine, the water is passed to do the work and to downstream the process. Its effectiveness remains exhaustive for cultivation of farms and reducing the dehydration problem. Compared…

IC Engines – Introduction
An Internal Combustion Engine (IC Engine) is a type of combustion engine that converts chemical energy into thermal energy, to produce useful mechanical work. In an IC engine, combustion chamber is an integral part of the working fluid circuit. Principle of operation: Air-fuel mixture in the combustion chamber (inside the cylinder) is ignited, either by a spark plug (in…

Heat Treatment Processes
Summarizes and definitions of the some common heat treatment processes like annealed, normalized, quench hardened and tempered are given below. Annealed: Annealed is the condition of a metal that has been heated above a specific temperature, depending upon its composition and then cooled down in the furnace itself or by burying it in ashes or…

Governor Types – Centrifugal Governor and Inertia Governor
Governor is a device used to maintain the speed of an engine within specified limits when the engine works in varying of different loads. Based on the source of controlling force, the governors can be classified into two types. Governor types are centrifugal governors and inertia governors. Centrifugal Governors : In centrifugal governors, multiple masses know as…

Essential software skills for Mechanical Engineers
1. AutoCAD ( A basic CAD software for design and drafting purpose) 2. Pro/Engineer ( A complete parametric 3D CAD/CAM/CAE software) 3. C Language (A programming language) 4. ANSYS ( An analysis or simulation software) AutoCAD and its Capabilities AutoCAD is a drafting software which involves drawing of 2D objects as well as 3D modelling. Importance of AutoCAD Being a Mechanical student, one need to do final year…

Detonation or Knocking in IC Engines
Detonation or knocking in I.C. Engines – The loud pulsating noise heard within the engine cylinder of an I.C. engine is known as detonation (also called knocking or inking). It is caused due to the propagation of a high speed pressure wave created by the auto-ignition of end portion of unburnt fuel. The blow of…

Difference between 2 stroke and 4 stroke Engine
The stroke of an engine is referred to the distance covered by the piston from the top dead center to the bottom dead center. If the piston moves two times then the engine is called two stroke if the piston moves four times then the engine is called four stroke engine. The crankshaft’s rotation is…
