Engineering Jokes

Interviewer: Why is a thicker conductor necessary to carry a current in A.C.as compared to D.C. ?
Candidate: An AC current goes up and down (drawing a sinusoid) and requires more space inside the wire, so the wire has to be thicker.

Interviewer: How will you tell if that wall outlet carries AC or DC?
Candidate: I will put my finger in. If it is pushed away, it is AC. If it gets stuck, it was DC.

Interviewer: How will you reverse direction of an Induction motor?
Candidate: I will remove the four bolts at the base, turn the motor around, and put back the bolts.

Interviewer: How do you start a synchronous motor?
Candidate: Vrrrrrrrmmmmmmmmmmmmmmmmmmm (in rising pitch)
Interviewer: Stop! Stop!
Candidate: rrrrrrrmmmmmmmmmmmmmmmmmmmm (in falling pitch)

Interviewer: How do you limit surge current within an integrated circuit?
Candidate: By using a miniature circuit breaker.

External (to student) : "Why does a capacitor block DC but allow AC To pass through ?
Student: See, a capacitor is like this --- --- , OK.

DC comes straight, like this ----------, and the capacitor stops it.

But AC, goes UP, DOWN, UP DOWN and jumps right over the capacitor!"

Examiner: "What is a step-up transformer?"
Student: "A transformer that is put on top of electric poles."
Examiner (smiling): "And then what is a step-down transformer?"
Student (hesitantly): "Uh - A transformer that is put in the basement or in a pit?"
Examiner (pouncing): "Then what do you call a transformer that is installed on the ground?"
(Student knows he is caught-can't answer)
Examiner (impatiently): "Well?"
Student (triumphantly): "A stepless transformer, sir!"

TOP FACTS ABOUT ENGINEERS


Engineers at work:

Assignments solved by one and then carry out mass transfer operations throughout the class.
_____________________________________________

The most important machine for Engineers: Xerox Machine (Without which assignment Completion wouldn't be possible)

Top two Engineering Rumours:

'Did you hear the results are being put up today at 5:30pm'

'Did you hear the exams are postponed by two weeks'

Common Engineering Dialogues after a paper:

'What is this pal, 60% of the paper was out of the syllabus
(syllabus =>> previous year's paper & lecture notes)'

'This was the worst paper set in the entire engineering history'
'I am failing'

GOOD ONE

Once all the scientists die and go to heaven...They decide to play hide-n-seek...Unfortunately Einstein is the one who has the den...He is supposed to count upto 100...and then start searching...Everyone starts hiding except Newton...Newton just draws a square of 1 meter and stands in it right in front of Einstein...Einsteins counting......97,98,99.....100........

He opens his eyes and finds Newton standing in his front...Einstein says "newtons out..newtons....out....." Newton denies and says i am not out...He claims that he is not Newton...All the scientists come out and he proves that he is not newton...how?

His proof: Newton says:I am standing in a square of area 1m square...That means I am Newton per meter square...Hence I am Pascal...since Newton per
meter square = Pascal, Pascal is OUT.
