Structure
The following differences between a machine and a structure are important from the subject point of view: Structure1. the member of structure do not move relative to one other.2. Structure…
Kinematic link (or) element
A machine part or a component of a mechanism is called a kinematic link or simply a link. A link is assumed to be completely rigid, or under the action…
Introduction to mechanisms, velocity and acceleration analysis of mechanisms
Mechanics: It is that branch of scientific analysis which deals with motion, time andforce. Kinematics is the study of motion, without considering the forces which produce thatmotion. Kinematics of machines deals with…
What Is Theory of Machines
Theory of Machines may be defined as that branch of Engineering-science, which deals with the study of relative motion between the various parts of a machine, and forces which act on…
Construction and Working of domestic refrigerator
Evaporator is a heat exchanger which removes the heat from stuffs or foods to be cooled by evaporating (Evaporation condition: BP < Evaporation temperature) the low pressure liquid refrigerant while passing through…
Working Principle of Water Heaters
Almost everyone uses a water heater in day to day life. But how many of us have the exact idea of how it works and how the cold water is…
Why compression ratio of petrol engine is kept low compared to diesel engine?
What is the need of high compression ratio? Today every machine is expected to give higher efficiency. When we talk about petrol engine and diesel engine whose thermal efficiency is directly related to 'compression…
Making More Efficient Combustion Engines
Improving internal combustion engine efficiency is a prime concern today. Engineers have devised many methods like turbocharging, cam-less engines, direct fuel injection, VIT, regenerative braking, etc. In this article we…
What is Rocket Propulsion?
This article will review the basic characteristics of rocket propulsion, including the application of Newton’s Third Law of Motion, types of propellants, forces acting on rockets during flight, and more.…
