Hi everybody, I'm in somewhat of a career conundrum. I'm 24, I've graduated from the University of Maryland in May of 2010 with a BS in Civil Engineering. I've been working for the past year for a fairly prestigious engineering firm, and while I do like my work, I've come to decide over the...

What is correct? That the probability of failure is 0.13 per year? I still seem to think that I can get a "probability" of failure out a failure rate.

Hi all. Probability definitely isn't my specialty, and I've run across this problem at work. There's one gate valve that isolates two 2400 psi hydrogen gas banks from each other, and I'm trying to find the probability that it fails in one year. I've done some digging and found failure rates...

You're never too old!

I know this thread is a bit old, but I'm a Maryland graduate with a Civil Engineering degree. It's a BIG school, but their Aerospace program is one of the best the U.S., so you can't go wrong. It's also great because of the quick access to DC if you want to have a night out, and there's a...

I think I may have gotten an answer...but I'd like some confirmation of my work if you guys wouldn't mind. First off, S = Shear F = Flexure P(S \cup F) = 0.2 P(S | F) = 0.8 P(S \cup F) = P(S) + P(F) - P(S \cap F) P(S \cup F) = P(S) + P(F) - P(S | F)P(F) (conditional probability...

Homework Statement A concrete beam my fail by shear or flexure. The failure probability in shear is equal to the failure probability in flexure, and the probability of failure in shear when the beam is loaded beyond is flexure capacity (ie, it has already failed in flexure) is 80%. Find the...

It will be traveling down and to the left, the particle will go southwest of its current position if it's allowed to move.

The charges of q0 and q3 are positive, therefore it's a repulsion affect. However, I'd think the magnitude of the overall force would depends on how big the charge of q3 is. I have a feeling I'm overlooking something blatantly obvious. Thanks again for helpin out.

Bump! Still seeking some assistance with this :). Anybody have any idea what's wrong with my answer above? Thanks!

Okay, well I tried this answer, which makes sense, but mastering physics says it's wrong. What looks wrong?

Okay, so I'll call the equation I found A. So it would simply be F= Acos(45)y + Asin(45)z. But sin(45) is undefined, which just brings up another question, haha. EDIT: STupid mistake, sorry. arcsin(45) is undefined.

The pythagorean theorem, which is what I used to distance for the d^2 in the equation for the magnitude I found. Both the base and height of the triangle are d2. So the hypotenuse is \sqrt{2d\stackrel{2}{2}}. But how can that factor into the coulomb equation I found? EDIT: Would I just use...

Thanks for the replies guys, and I know that's exactly what I have to do, I'm just unsure of how the equation would split up. I'm confused because the force is the magnitude of the force along the hypotenuse, how can that be split up into two vectors? PS. I'm not a huge fan of mastering...

Homework Statement Homework Equations It's given in the answer box. The Attempt at a Solution Basically, I found that equation for the magnitude of the force experienced from particle 0 by particle 3. I know it to be correct. However, vectors have always confused me, could...
