During practical examination External examiner asked, “What material is
used for wattmeter base?”
I kept silent.
He probed further, “You should know the answer, being from mechanical branch?”
I said, “I know it is stainless
steel but then you will ask ‘why stainless steel’, for which I have no answer.”
The examiner laughed and replied,
“I too do not know why it is made of
stainless steel!”
