I’m testing too.

{42 x 3}[ Eeff /E], Δ = 5wL4 / 384 EI Δ = 5wL4 / 384 EI
Δ = 5wL4 / 384 EI, The deflection for a uniformly loaded simple beam. To keep the units straight, w must be in lbs./inch and L must be in inches. Or, w can be in lbs./ft. and L can be in feet, but then the numerator must be multiplied by (1728 ʺ3 / ʹ3).
I was going to do some experimenting on this thread, on SUN 13FEB11, because I have had the same trouble posting formulas as DRP has had. I do most of my typing in my word processor and then copy and paste to the thread on the forum. I know how to use some of the special character and formating features on my word processor, but it seems that I can’t always get them to transfer meaningfully to the forum, seems the formatting doesn’t transfer or some such. And, if it becomes too much work, it just may not be worth it to me.
Well... I was fiddling with ChrisK’s system and its codes a bit, and all of a sudden all hell broke loose. I had my very own Uncle Bob moment, I thought I pretty much turned my computer into a boat anchor. Like I said the other day, in defending what I assumed was Uncle Bob’s frustration, this old guy gets easily frustrated with this computer stuff too. Nothing about the screen made any sense, the tool bars were gone so I couldn’t seem to do anything, including shutting the computer off, and after about an hour of that I just want to throw the damn thing out the window. And the fun part is, I have no idea what I did to cause the problems or how to rectify some of them. I rather like this forum business, but I don’t get a kick at all out of playing with the computer for the sake of playing with the computer.
