[FONT="Arial"]Hi all,
Some of you will find this a dumb question but my brain has seized up.
Q.
Imagine you have a canister, say 200mm diameter and 500mm high, and inside the canister you have a vertical bracket positioned in the centre of the bottom face of the can, and is about 250mm...
Hi all.
Just got a question to ask, I'm slightly puzzled by it.
Q.
Say that you have a sealed container and you put in it 50% helium and 50% argon and you leave it for a few days. Because argon is heavier than helium, would the most of the helium rise to the top part of the container...

Hi all,
Can anyone recommend a book on electrical motors that clearly explains and has plenty of examples on how to calculate the required motor power/rating for a automotive robot.
I'm trying to work out the required power to lift a robot arm, then somehow find the correct electric motor...
Hi all,
I was speaking to a design engineer and he mentioned that he uses Classical Finite Element Analysis in his work designing valves and cylinders.
Can someone explain to me what is Classical FEA, and how does it differ from FEA that you use in a computer program (Ansys, abaqsus,...)...
Hi,
I realized that, but I couldn't figure out how the book was doing the rearranging. I've been differentiating a few Inverse Hyperbolic functions, and I thought the reason that the book rearranged differently to me was that somewhere down the line it would become clear why it was done.

Hi,
My brain is not working today. So can someone please tell me what I am doing wrong.
(^2 = squared)
coshy^2 - sinhy^2 = 1, how do I rearrange this for coshy^2
I keep getting: coshy^2 = 1 + Sinhy^2
The book that I'm looking at has it this way: coshy^2 = Sinhy^2 + 1
Thanks
Obs
