When the potential energy of is given, derive the variational equation using the principle of minimum potential energy.
Problem :-
Derive the weak form of a simply supported beam problem.
1- If the diameter of a spherical water droplet is 100.0 µm, how much energy is required to increase the diameter of the water droplet by 3.0 µm The surface tension of water is 1.0 x 10-3 J/m2. 2- A metal crystallizes in a face-centered cubic lat..
Sometimes the partial fraction expansion is not needed in finding the inverse Z-transform- instead the properties of the transform can be used. Consider the function F(z) = z+ 1/z^2(z - 1) a. Determine whether F(z) is a proper rational function as ..
Design a half-wave rectifier power supply to deliver an average voltage of 9V with a peak to peak ripple of 2V to a load. The average load current is 100mA. Assume that ideal diodes and 60Hz. ac voltage sources of any amplitudes needed are avail..
Write the magnitude function for a third order Chebyshev filter having a ripple coefficient of 0.4. Do not expand. Also find the cutoff frequency.
Construct a Phasor Diagram to represent the source voltage, source current, voltage drops, VR, and VL across the resistor and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be includ..
Consider a source-free parallel RLC circuit having alpha =10^8 s^-1, omega-sub-zero = 10^3 rad/s, and omega-sub-zero * L = 5 ohm. a) Show that the stated units of omega-sub-zero * L are correct. b) Compute s_1and s_2.
An embedded SRAM contains 2048 8-bit words. If it is physically arranged in a square fashion, how many inputs does each column multiplexer require?
If the area of the wire is increased by 2/3 and the length is reduced by the same amount, find the new conductance of the wire if the temperature remains fixed.
What is the applications of normal probability distribution in electrical engineering?
Discuss how energy is stored in capacitors and inductors. Are the equations linear or non-linear How do you know? Discuss the concept of duality and why it applies to many fundament engineering concepts.
The airgap of a moving coil instrument is 2.0 mm long and has a cross-sectional area of 500 mm2. If the flux density is 50 mT, determine the total energy stored in the magnetic field of the airgap.
A capacitor, an electric resistance heater, and an impedance are connected in a parallel to a 120 volts, 60Hz system. the capacitor draws 50VARs, the heater draws 100 watts and the impedance coil draws 269 VA at a power factor. Find the Apparent P..
