Sorry guys, I misinterpreted the question. I'd delete this but don't know how.

Homework Statement The idling engines of a landing turbojet produce forward thrust when operating in a normal manner, but they can produce reverse thrust if the jet is properly deflected. Suppose that while the aircraft rolls down the runway at 150 km/h, the idling engine consumes air at 50...

I have that equation, but I just found out I don't have the symbolic math toolbox for MATLAB and that's why I couldn't solve the equation for beta. I used Maple to solve for beta and got a ridiculously long result.

I'm trying to write a MATLAB .m-file that will calculate the lift and drag on a supersonic airfoil using only the angle of attack, mach number, and geometry of the airfoil. I'm getting stuck on the oblique shock angle calculation because I cannot find an equation that is solved for the shock...

I need to classify a bunch of differential equations and this one has me stuck... 3x+1=4t Would this be zeroth order? Or should I just call it a quadratic equation? Also, I need to identify the homogeneous parts of these equations. I know what a homegeneous differential equation is, but how...

It's possible that the 2 year school offers an engineering technology program, not an engineering "science" program that will transfer into a 4 year degree's requirements.

I am having trouble forming the Global Stiffness Matrix for a planar truss. Does anyone know of any good online resources to help me with this? I've found a few, but haven't been much help.

Ok, thanks. No, I haven't tried the similar triangles because, well, I don't get it :rolleyes:

I ran through it a few times...I don't see where I'm losing a factor of 2.

Homework Statement Derive an expression geometrically for the radius of curvature of the following beam. This is part of a lab assignment for the bending of a simply supported beam with overhangs. ** I did this crappy diagram with AutoCAD, so I couldn't ( or didn't know how to ) include...

The moment, right? Going back to my "attempt at a solution", I believe I screwed up. For the cantilever, at x=0, y=0...and at x=0, dy/dx=0. I had put that at x=0,moment=0, which is wrong. Also, I'm going to need to use: @x=L,shear force=0...and @x=L,moment=0.

Homework Statement Determine the equation for the deflection curve for the cantilever supported at A with a load given by: q=q0*sin(\pix/L). Homework Equations The Attempt at a Solution I think this is pretty straightforward, but want to be sure. I did a similar problem with a...

LOL...for some reason, that site made me extremely angry. :mad:

Conservation of momentum. The total momentum before she jumps on the board=total momentum after she jumps on the board.
