Attempt at solution This is an old exam question. Am I correct to say the shortest path goes through M since M is in d(O,M) and d(D,M)? I don't know how to prove this and answer the question about the cost

Mod note: Moved from a technical math section, so the template doesn't appear. Hi I have a demand for 6 quarters of [29, 24,32,21,31,21] and can produce 25 units each quarter. I am trying to calculate how many units I have to deliver at least 1 quarter too late and also how many units I...

I'm trying my first design and want to make it successful before I actually make the product. I want to calculate what the stresses are and where they are likely to be. F is a varied load from -10 to 10 kN To find the critical points, should I check the points that i labeled A, B , C ...

Hi I'm learning how to use terminal at school but there is one part of my assignment Write a command file (a .bat file on Windows, an .sh file on OSX/*nix) containing the following command: 1. navigate to the folder C:\Temp (you may assume it exists, you should create it on your own...

Thanks. I copied the problem from a pdf i found online to post here. But I guess they changed the numbers in the problem cause it's not the same numbers as in my book. So the solution manual doesn't show the correct answers to my book even though they are the same editon.

I'm having problem with task (a) in this problem The question My attempt The solution Why don't I get the same after I take the partial fraction using my calculator? And where does this R(s)=1/s^2 come from

Hi I'm doing Fourier analysis in my signals and system course and I'm looking at the solution to one basic problem but I'm having trouble understanding one step Can anyone explain to me why becomes From Eulers formula: http://i.imgur.com/1LtTiKX.png for example the Cosine in my problem. I...

Hi Just got the data from a tensile strength test on a axle we did in school. Before it broke: http://i.imgur.com/1ddrZ7j.png The data : https://www.dropbox.com/s/xf5m8m8gyco561n/data.txt column 1: the displacement in mm column 2: the force in kNI'm supposed to plot a stress strain diagram...

Prove that this equation satifies the Euler-bernoulli beam equation which is given by Cany anyone help me with this. Can wolfram alpha do it? It has so many values and I'm not comfartble with doing 4th derivitives

I'm trying to make a banded matrix in MATLAB like the one in my picture. I'm trying to use the spdiags function but I'm not going even close to getting the same matrix. I have tried the help in Matlab but have had no luck yet. How can you tell the bandwidth is 7?

Can anyone help my to see why my solution is wrong because the in the solutions it says that it is not time invariant

The box signal is just like a rectangle plotted with stem. i really don't have the formula but it just a vector with a few ones in it. No i get to choose all my N,N1 and N2 values. But i have to justify why i choose them. It's just to test the fft function

Hi I'm trying to use the fft function in MATLAB to compute the discrete Fourier transform of a box signal. I'm told to assume that the signal x[n] is periodic with period N and the vector contains one period. x[n]= box [n] I'm am going to use these commands to make my vector...

Discrete signal x[n] is shown in the first picture. Sketch x[2n] Answer Can anyone ecplain why x[2n] is like that. I can understand how to plot it if i have a continuous time signal

A cylinder (800 N) is beng kept up by the the poles. Find the Foces in A and B and the tension in the wire I have a bit unusual statics problem. Never done a problem simular to this. I know about Fx=0 and Fy=0 and the moments at any point is=0 Can anyone help me to get started...
