Jokes for serious people

This semester I'm teaching an undergraduate course on functions of a complex variable.  A student has just sent me a message:

Q: Why did the mathematician name his dog "Cauchy"?

A: Because the dog left a residue at every pole.

I received an email several weeks ago with the following quote:

Research on meshless methods and comparison between these methods

Submitted by sadook on

Hello everybody,

I am doing a research on meshless methods  and I want to know about these methods, the difference between these methods and the method the most used and if it is possible, I want to get some codes of these methods.

Thank you,

Cordially,

Beam Theory for larger cross section

Submitted by ravitejk4u on

hi,

i want the mid point deflection in case of "four point bend test" on a specimen of length 140mm, width of 40mm and thickness of 10mm.

Problem is that, beam theory is valid if the cross-sectional dimensions are less than axial dimensions. Here this condition is violated. i had modeled the specimen in Abaqus and the diffection at mid point is almost double that of the actual diffection calculated from beam theory. 

how can i find the theoritical difflection at mid point in this case?
