Difference between Engineer and a Degree Holder.

               What should a student do, to turn into an Engineer?

   

Now a day's people with B.Tech degree are more than that of engineers.Why is this happening? Inorder to demonstrate this I would like to introduce a concept to u that is.Pythagoras theorem since our childhood we are familiar to this concept.

                      
                   AC=Hypotenuse

                     BC=Opposite

                     AB=Adjacent

  According to Pythagoras theorem

            (AC)^2= (BC) ^2+ (AB) ^2

Since beginning of this blog I said it as a concept so faculty or teacher teaches this concept. We students learnt this concept (part of teacher student business is done).Now it is our job to use or implement this concept.

Applications of   Pythagoras Theorem

1) You live on a 5th floor on a building near Downtown LA. Suddenly your freaking neighbor on the 4th floor starts a fire. All because he caught his girl chatting with another guy. Not that she was talking to a colleague on HP. Not that we know. He bashes the whole apartment to his uppermost delight. He leaves her unconscious and you happen to see him leaving, and run to her door. and take her out on the hallway and flames catches up with you both. The only way to stay alive is keep going up. You call 911 and they get hold of your emergency.

A fire engine gets there in 6 minutes. You are by the window and hope the telescopic aerial ladder will be able to reach you both. A fireman does a quick calculation:

We have 5 floors, each floor is 8.5 feet high (Hurry up Lord!!)Total height of the target is 8.5x5= 42.5 feet

The closest an Engine can get (sideways) is roughly 7 feet (Lord please!!)

We don't worry about nothing else and apply the theorem:

(42.5)² + (7)² = (ladder span needed) ² = L²

The fire-guys will solve this equation in 5 seconds...

1806.25 + 49 = L²

L² = 1855.25 Then L=43.072613108563544 or: L=43.1 FEET

 

The aerial span needed is about 43 feet, and luckily the fire engine mount aerial ladder can be extended up to 50 feet. Our 'finest heroes' can go up, with no problem at all.

2) Distance Measuring Equipment: - critical instrument used in calculating distance from aircraft to the airport (run way).

Vertical height is given by altimeter. (BC)

Slant height is calculated using D.M.E (AC)

Using Pythagoras theorem 

We can calculate (AB) which is (horizontal distance) nothing but distance between aero plane and airport.There are hundreds of applications of Pythagoras theoremSee this is how we apply a concept to real time problems.Task of an engineer is to find a concept which could eliminate the problem. 

I believe applying science to real time problems is engineering.
