As we all know about the turbine. They have vast application and can be classified in different ways. According to water flowing through the turbine runners, turbines are classified in two categories i.e. impulse turbines and reaction turbines. Pelton wheel turbine is the type of impulse turbine but here we talk about only reaction turbine. …

Capstan and turret lathes are semiautomatic lathes. Semiautomatic means machining is done automatically but some other functions like changing of job/work piece and setting of tools are done manually. These are the modified version of engine lathe. It is an example of advancement of technology in manufacturing industry. Construction of turret/capstan lathes is similar to …
Lathe is an important and widely used machine tool used in the machining process. Sometimes it is called as mother of all other machine tools. The main function of the lathe machine is to remove excess material from the job and give it require size and dimensions. Lathe rotates the work piece about an axis. …
We all have heard about shock absorbers. As the name implies, it is used to absorb shocks occur during driving on uneven roads. It is also used for stability of vehicle under sudden acceleration or braking condition. The most common type of shock absorber is Telescopic type hydraulic shock absorber or sometimes called telescopic shock …
Today we will learn about cone clutch, its principle, construction, advantage, disadvantages and its applications. Cone clutch is one type of friction clutch which is used to engage and disengage engine shaft to the transmission box shaft during changing gear ratio. It is one of the oldest types of clutch used in automobile industries. This …

In my last lecture we have learnt about strain and types of strain. Today we will learn about types of stress. We know that when a body is under loading some kind of stress developed in it. Mathematically this stress is the ratio of the applied force to cross section area of the body. If …
Hello friends, Hope you are doing well. In our last lecture we have studied about stress and strain. We have learnt about basic concept behind it. Strain is a measurement quantity which is ratio of change in length to original length under loading condition. But when we stretch a body, its dimensions changes in all …
