    B Deriving the gravitational constant factor for lbf

    I have never had to use the English Engineering System so I am having a bit of a struggle here. I understand the concept of an inconsistent system of units. I understand the following 2 statements: 1lbf = 1lbm x 32 ft/sec^2 1lbf = 1slug x 1 ft/sec^2 When given a problem that is asking for the...

    How Do You Compute the DFT of Periodic Signals?

    Homework Statement Find the discrete Fourier transform X[k] = DFTn {x[n]} of the following periodic sequences x[n] = x[n - N] with period N: (a) For n = 0 . . .N - 1 we have x[n] =\delta[n]. (b) For n = 0 . . .N - 1 we have x[n] = \mu[n] -\mu[n - K] with K < N. (c) x[n] = cos( (2*pi*M*n)/N...

    Engineering RLC circuit step response time domain

    ye lol i just used matlab syms s C=...equation.. c=ilaplace(C) if anyone wants to post how to do it by hand, go ahead. I don't need to do it by hand for this particular assignment. Thanks for help. I do see now how to do it band nut i am to lazy to do it.

    Engineering RLC circuit step response time domain

    This is more of a math question but i feel like i will get more help among Electrical Engineers. I successfully found the step response of an RC circuit in the time domain using Laplace Transforms. But i can't seem to figure out how to do it with an RLC transfer function. I have the following...

    Coordinate Geometry: Point Division in Ratio 2 : 5

    I thought A and B are just two points. So, the line between them is B-A (8-1, 12+2,-3-4) You get (7,14,-7) Than you divide this by seven because there are seven parts total (ratio 2:5). You get (1,2,-1) --- This is for one part. So the answer is (1, -2, 4) + 2(1,2,-1) = (3,2,2) I am not sure...

    What is the Length Integral Problem at Point (1,1)?

    Hi, could someone help me with this problem. Find a curve through the point (1,1) whose length integral is L = \int_{1}^{4} \sqrt{1+ \frac {1} {4x}} dx Thanks PS: Is this the right place topost it? I just thought that differentiation is closely connected to integration.
