The flat circular disk rotates about a vertical axis through O with a slowly increasing angular velocity ?. Prior to rotation, each of the 0.44-kg sliding blocks has the position x = 22 mm with no force in its attached spring. Each spring has a stiffness of 375 N/m. Determine the value of x for each spring for a steady speed of 258 rev/min. Also calculate the normal force N exerted by the side of the slot on the block. The force N is positive if it pushes from the side labeled A. Neglect any friction between the blocks and the slots, and neglect the mass of the springs.
Using the time independent one dimensional Schrodinger equation, find the expression of the allowed energy levels for an electron in infinite potential well of width Δz= L (i.e. solve the differential equation and apply B.C. to obtain En)
a) Based on your decision create a sampled signal of the sum of the two sines, and plot the magnitude of the zero centered FFT with property frequency annotation. Did it work Check with the data tip tool.
Explain Capacitance of parallel plates capacitor, Relative permitivity is 500, The area is one square meter, The distance between the plates is 0.001 meters
A synchronous generator rated 1350 MVA at 0.9 pf, 22.5-kV, Xs=11.6% is connected to a power system through a 1500 MVA, 7.9% 24-kV/230-kV generator step up transformer. The power is generated into a 230-kV system.
The purpose of this project is to design a device that would remotely control (from a Bluetooth-enabled mobile phone for instance) at least two actuators (e.g. relays and switches).
A 75 lossless line is terminated in error with a 93 resistor. A generator sends 100 mW down the line. (a) What is the SWR on the line (b) What is the reflection coefficient
Construct the adder for 2 digit decimal numbers presented in BCD code. 4 bit binary adders and additional logical gates. The BCD adder for each decimal digit can be implemented with two 4 bit binary adders where the second adder.
F = B'D' + A'B'C + ABC + CD' Draw a circuit for this function using only AND , OR, and NOT gates. The function calls for two 3-input AND gates and one 4-input OR gate. All you have available, however, are 2-input AND and OR gates
Using this method, create and test a minority vote circuit, a circuit designed to indicate when one or no inputs are HIGH. Determine the appropriate SOP equations, enter, compile, simulate, download, and test your solution.
A series circuit has a DC voltage source (56 volts), a resistor, (72 ohms), a capacitor (82 farads), and a switch. The capacitor is initially uncharged and the switch closes at t=0.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
