I do, indeed, know this. Although, I have no experience building airplane models. My only experience is with cars. The incite is interesting. Thanks!
I would discuss this with my professor and/or one of my peers, but I'm taking an internet class and not one single peer responds to class...
The question as presented to us was extremely vague. It did not clarify if the state variables were initial displacements, or if they were relative displacements from Y=0. I took them to be displacements from their rest positions and wrote the state equations with that assumption. Sorry for...
Homework Statement
I was tasked with finding the equations of motion for an the airplane model pictured below. Mass 1 and Mass 3 represent the wings. K1 and K2 are linear springs that represent the stiffness of the wings. M2 is the fuselage and M4 is the landing gear. K3 is the linear...
Well its been a while. Since I posted and the project I posted it for was long since been turned in. Thanks for the input and the link though. Its quite helpful since this information just doesn't seem to be recorded anywhere.
I don't quite understand how the modified goodman equation can be applied to a multiaxial stress state. The explanation given in my stress analysis class has been quite confusing and verbose so I've come here to see if I can't get a better understanding.
First I'll lay out what I think to...
See, that's what I think it should be (and yes I'm looking for the first term a(sub 0)). But the answer key gives the answer I posted above. I'm beginning to think its wrong. Although, going by what we think the answer is, the transform of the function f(t)=1 would just be 0, which doesn't...

The Attempt at a Solution
So I feel quite stupid because this...
Hello,
I need to take the integral of 2/(Y+1) over the interval [2,0]. The only analytical method I know is to take the anti-deriviative of the integrand and subtract the function values at the endpoints of the interval. I know that the anti-deriviate of (x)^-1 is ln(x), but I don't know how...
I need a quick check on my math. Derivative of composite function y=sec^2(X) where X is a polynomial.
Does it equal:
y'=(secXtanX)(secX)(X)(dy/dx)+(secX)(secXtanX)(dy/dx)(X)+(secX)(secX)(dy/dx)
I'm a little confused on applying the product rule and the chain rule to this function.
