Hiya I'm revising for an Aerospace Dynamics Exam... I've hunted high and low for a couple of quick definitions but can't find any! How do i define the neutral point and the static margin of a wing? Any help/suggestions of where to look gratefully recieved! Thanks Phiska

Thanks! Clarifies things for me. Phiska

Hello I'm researching IIR filters: Butterworth, Chebyscheff 1 and Elliptic types. I've been using MatLab to model them and analyse the responses. However, I'd like to know what these three filters are particularly suited to... i understand that Low-Pass filters are typically suited to...

re-entry angle, ballistic coefficient, initial altitude, initial velocity, density of atmosphere at different altitudes etc

Hi, I need to plot as a function of time, the altitude of a capsule bringing astronauts back from space. I have all the values required in order to calultate it but I'm not sure how i plot it as a function of time? Is it simply a differential matter? Your help is much appreciated...

Thanks everyone for your help!

That definitely sounds like a plausible solution. I will have a go and see if it works out, and will let you know. Thanks a lot

I'm sorry, do not intend to appear rude. I am very grateful to everyone who takes the time to help me.

If i have two cantilever beams with a vertical prop between the free ends as shown in diagram, how do i find the load on the prop? I have the deflections of the beams to be: v (top beam)= (PL^3)/(3EI) v(bottom beam)=(5WL^3)/(48EI)-(PL^3)/(3EI) the prop is of diameter d, and length a...

No, its a similar example, with the same arrangement but a different question. This time I'm looking at the load on the prop.

If i have a simply supported J Section beam, when I'm calculating the max deflection, what value of I do i use? I have already had to calculate Ix, Iy and Ixy. I would imagine that as deflection occurs along the y-axis that i would use Iy. Or do i use Imin? I have already calculated...

Thank you so much... you've been really helpful!

why is it that for the maximum deflection it is (3L-L/2) rather than just (L-L/2)? I want to understand what is going on as well as getting the correct answer.

It simply states in the question that the distance, a, between the beams is maintained by a prop of diameter, d.
