A Joke

Hmmm let's see if I got the hang of this...

Four Bankers walked to the top of a hill, they were slightly out of breath.

An Englishman, an Irishman and a Scotsman walk into a bar. Due to their combined weight being greater than the shear strength of said bar, the bar bent slightly, and had to replaced.

You fail at Engineering, if it was greater than the shear strength of the bar the bar would shear in half not bend, so that is just stupid.

What you were meant to say that their combined weight excerted a force which caused the stresses in the beam to exceed the yeild stress of the material and thus the beam bent.

What's the difference between a buffalo and a bison?

One is of the genus Syncerus Caffer and native to only Asia and Africa, the other is of the genus Bison Bison found in North America.

Firstly, Syncerus caffer and Bison bison are species, not genuses. Secondly, the final half of a species name is never captialised.

Thirdly, I'm pretty sure there is a European bison species as well.

Paddy is being interviewed for a job in the Metropolitan Police Department,
"Paddy....you are undercover....it's the middle of the night....your cover is blown and you're being chased by a car full of terrorists at 80 mph.....what should you do?"

"Uhhh......90 mph" said Paddy.

Well done, you passed my test of seeing who would spot the obvious flaw. After going on to test the bar using the Charpy Test method, I can safely say that the bar was made out of steel, which, at the time, was in the upper region of it's Ductile-Brittle Transition temperature range, and therefore the stress only caused some mild plastic deformation, and all was fine in the world.

The charpy test is for checking the toughness of the material and has nothing to do with the dutile behaviour of it. Its normally only applicable for tool material (drill bits/hammers) and not standard beams.
