rcgldr, I don't like you. You don't read. I had already figured out how I was attaching it, and needed magnitudes of the tension in the cables. Both of your posts were useless to me.
The correct answer was to simply add the third direction to my moment equation, I'm done now.
Mod, please...
Hey all,
I'm working on an experiment and we have a frame which will be exposed to loads in all directions. I'm trying to analyze how to best secure it and am having trouble considering the 3D analysis, while the 2D analysis seems rather simple to me. I was informed the 2D analysis is...
So for example, my function is:
\frac{d^2y}{dt^2}=-9y
So converting it into two first orders would be:
\frac{dy}{dt} = z
and
\frac{dz}{dt} = -9y
So as I understand,
y' = \int{\frac{dz}{dt}} = -9yt
When I plug this into Matlab (with a Euler's ODE solver and initial...
I found out I did it exactly right. When the second derivative is negative, the system is unstable and when it's positive, the system is stable.
What's going on is at the top position the spring is pulling on the rod and keeping it in place, so without excess force pushing on the rod, it will...

I was getting the feeling that I'm lacking information too.
Verbatim: Assume that “x” = 6 ft. If Ed stands at “x” and Schueller at “x/2” and they start at a horizontal position, how far (phi in degrees) will they be able to turn the bolts?
Ed weighs 250 lb, and Schueller weighs 100

1. The Funny Intro:
The summer before he entered high school, Prof. Schueller’s had to run the farm because
his father had an emergency appendectomy. To adjust the “thread” (the width between
the wheels) of a John Deere 4020 tractor, a torque of about 1600 ft-lbs. was needed to
loosen...
I hope somebody's up tonight, this is due in the morning and I'm so close.
So I was assigned to solve this differential equation using laplace transforms and although I (think I) can solve it, I'm not getting the same answer that Maple spits out.
The DE is:
x'' + 2x' + 5x =...
Well stay with me here...
I was unsure and that's what I was asking about, now as I understand it my new equation should be:
P(t) = (16543)\Sigma[\frac{(0.095t)^n}{n!}]-16571
True, the P(t) = a t^2 + b t + c is incorrect for the original DE I gave you, but it is correct for a different...
