The purpose of having a brake system is used in automobiles to slow down or stop the vehicle by converting its kinetic energy into heat energy. Classification of Brake system: 1.Based on mode of actuation: The foot pedal operates the foot brake (also called the m…

The highway or the road structure must be designed carefully for the traffic load to be carried, physical and geological features, climatic conditions of the locality, and various other factors that would affect the stability and utility of the highway roads. For desi…

In physics,   energy   is defined as a property of objects that can be transferred from one object to another or converted into different forms of energy. Energy is the capacity to do work, generating heat and emitting light. Heat is the ability to change an object&#…

The problems of mechanics can be solved by  Newton’s laws of motion . The three laws proposed by Sir Isaac Newton are described as follows. Newton’s First Law of Motion: Newton’s first law of motion states that every object will remain at rest or in uniform motion in a…

Several machine tools gradually increased until the 20th century and decreased based on Group Technology.   However, machine tools are broadly classified as follows:   1. According to the direction of the central axis : Horizontal center lathe, horizontal borin…

Slow forward and quick return mechanisms are to be found on some metal cutting machines, digital printing machines and digital scanners. The output gives a slow forward linear motion followed by a quick return to the start position along the same path. Two of the most…

Natural gas: The main constituents of natural gas are methane (CH 4 ) and ethane (C 2 H 6 ). Its calorific value is nearly 21 MJ/m 3 . It is an alternate fuel for internal combustion engines, such as liquefied natural gas (LNG). Coal gas: It mainly consists of hydr…
