1.AIM :  To calculate the drag force experienced by the cyclist. To plot a graph between Velocity of cycle(v) to the drag experienced by the cyclist (Fd). To plot a graph between Drag Coefficient ( C d ) and Drag force( F d ).   2.Governoring Equation   F d =  0.5 * C d * v * v *𝞀   Where, F d =  Drag force  C d =  Coefficient of drag v  = Velocity of the cyclist 𝞀 = Density of the air   3.Objective of the project   To write  a MATLAB code that will help visualise the graph as mentioned above.   4.Procedure   When a cyclist moves in a direction it experiences a resistive or friction force. In fact, there are a lot of forces which may act on the cyclist during his run, like friction forces between road and tyres of the bicycle,force of friction between chain and sprocket etc. But for our consideration we are taking into account the force which is experienced by the cyclist due to air,which ...

It was Sunday morning, as usual, i was on rest after my breakfast. I didn't worked or something but still i was on rest, just because i was satisfied with my life somewhere. I am a B.Tech final year student and rest is like poison to me. back to topic,                         when i was resting on bed, the door knocked twice.when i opened the door, a Gardner was standing in front of me.On the outer wall of my home some grass and small plants were grown, so he told me he will pluck of grass and plants and I need to pay him a sum of Rs 40. I replied," I need to talk to my father". He replied,"why you need to talk to your father, this is my job, i have to do it or any other Gardner                          will do. i am hungry and i am asking for job not for food, so please let me do it" I replied,"I need to talk to him." after saying this i left the door. ...

C ONCEPT OF A UTOMATION Topic -I AUTOMATION  Derived from Greek Word “Automatos”  Automatos means self acting  Started in 1940 by US automobile industry for handling of parts'  Till 1950 used on small scale for simple shape items with help of mechanical devices  After that used on large scale with help of computers DEFINITION OF AUTOMATION It is a process of following a sequence of predetermined operations with little or no human involvement using specialized equipment and devices that perform and control manufacturing process. DEFINITION OF AUTOMATION A process in industry where various production and controlling functions are converted from a manual process to an automated process. SOCIAL ISSUES OF AUTOMATION 1) Impact on employment/unemployment • Decrease in jobs of Manufacturing •Increase in jobs of IT sector •Decrease in jobs of Unskilled and Semi-skilled Workers •Increase in jobs of Skilled Worker. SOCIAL ISSUES CONTINUE 2) Better working Condi...

Corrosion and its prevention Corrosion  is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment. contents of notes What is corrosion ? types of corrosion details abut dry corrosion. Mechanism of corrosion. Nature of oxide formed PILLING BED WORTH RULE Rate of diffusion of metal ion.
