Two cover plates, each 1/2 in. thick, are welded to a W27 X 84 beam as shown. Knowing that σall = 24 ksi for both the beam and the plates, determine the required value of
(a) the length of the plates,
(b) the width of the plates.
Calculate the overall heat transfer coefficient (U) for the assumed tube diameter, finshape and material. Use correlations to estimate hot-and cold-side convectioncoefficients, conduction resistance, contact resistance (if any), and fouling resist..
Give an example of an RC circuit whose transient behavior cannot be modeled by having a function generator with square wave output replacing the mechanical switch.
Please list the properties of Discrete Fourier Transform. Explain each property with an example to show what it means physically and explain the physical meaning of Z Transform
A 2 GHz and 100 Watt transmitter is connected to a transmitter antenna with a gain of 12 dB. A 20 dB receiving antenna is placed 10 kilometers away, in what we assume to be free space, in the direction of maximum gain.
