Thanks for the reply. I realize it is not typical. I actually am currently working for Boeing. However. None of the materials we use are in the same class as this as we really aren't concerned with low cure temp and obviously have autoclave capabilities. I wAs sort of curious of...
Hey guys,
I know that I will have to get an actual quote from one of the material makers, but curious if anyone has a ballpark idea of how much low-temperature curing prepregs cost (10$/lb...100$/lb ? I have very little clue here). The most interesting ones I have seen so far are Hexcel M34 and...
Thank you very much. I wasn't entirely sure if that was what the matrix was claiming with the dotted lines between them (maybe thought this meant multiplication?) we really be we did much work with matrices other than an intro linear course.
Thanks again! Checked it and got the right answer.
Alot of what engineers do is reduce costs and increase production (which reduces costs) Although like tyger said, its not always easy in a down economy its much better off than most other disciplines, because when companies cut costs, engineers almost always have a hand in it, other than when...
I think that we would want to make an equivalent load at the mid point and evaluate how different that would be and then carry that through. (so our load at point Y is at a different point relative to the neutral axis, assuming we are both times pushing down correct??)
Homework Statement
This is the equation for stresses and strains in a multilayered lamina. The actual purpose is irrelevant as I just am unsure what exactly the equation is saying (is it A * B * B^-1 * D^-1)
I am unfamiliar with this matrix syntax.Homework Equations

Evo,
Thank you very much for your response. My intentions are to have a computer at a designated location, Y, and for me to be able to use my computer at location X but appear to be at Y. I will be looking into this further since it seems like the consensus is that a VPN is not what will...
Thanks for your response rc, I was under the impression that proxies were really easy to detect (again I don't really know much about all of this) and I just knew that using a VPN was an idea that I had heard thrown around before.
Hello guys,
I have recently been looking into VPN technology and my limited computer knowledge seems to lead me to believe that a hardware VPN >>> software/website VPN as far as it being secure for not showing the users true location. My interest in a VPN is to be able to be at location X and...
Hey guys,
I have been trying to make an AHK or macro that can perform a very simple 5 or 6 keystrokes multiple times. It is a task that I do at work that while it is very easy, becomes tedious over time. I tried to look into making an AHK but I haven't found out the syntax for it really. I know...
Homework Statement
A cantilever beam has uniform load w over a length of L as described by the eq.
EI y'''' = -w y(0) = y'(0) = 0 y''(L) = y'''(L) = 0
EI are constants
find y(x)
Homework Equations
L[y^4] = S^4*Y(s) - S^3*Y(0) - S^2*Y'(0) - s*Y''(0) - Y'''(0)

Lane,
Thank you so much for your reply. Sure enough it was on my exam today (which is killed!)
Was very uncertain about small parts of the rank, but you cleared it up.
Thanks!
Ben
LaneDance,
Thank you for your reply. Would it be accurate to say than that in the first problem the rank of matrix A could be interpreted as being 3? Since there will be 3 rows so the maximum would be 3? And I don't know how to interpret when the rank of A is greater than the augmented matrix, I...
Homework Statement
Given the following conditions, determine if there are no solutions, a unique solution, or infinite solutions. (Matrix A|B = augmented matrix).
Just in case anyone viewing needs a little refresher... Rank = number of non zero rows in the matrix.
