A 2722-kg weight is being pushed up an inclined surface at constant speed by a cylinder. The coefficient of friction between the weight and inclined surface equals 0.15. for a pressure of 6.9 MPa, determine the required cylinder diameter.
the length of a short-circuited stub of characteristic impedance Z (OS) =100 ohmns which, upon placement in shunt with the line at the 1 + jbn admittance point, produces impedance matching on the line so that there exists no reflected wave to the ..
Draw a state diagram for a synchronous sequence detector that will detect every occurence of the sequence 111001 in a serially transmitted message of any length. The sequence detector should detect overlapping sequences as well as individual occur..
The bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12 kOhms
Use Matlab to verify the above results and determine: a. The starting torque b. The maximum torque c. The slip at which the motor develops maximum torque d. Draw the torque-speed characteristic of the motor

A 13,800/480 V three-phase Wye-Delta-connected transformer bank consists of three identical 100-kVA 7967/480-V transformers. It is supplied with power directly from a large constant-voltage bus.
In a balanced three-phase system the Y-connected impedances are 3∠60°Ω. If V_bc=480∠-75° V, find current of phase "b" in polar form.
b. Draw the logic diagram, using the original Boolean expression. d. Obtain the truth table of the function form the simplified expression and show that it is the same as the part one. e. Draw the logic diagram from simplified expression, and compare..
1) A 1.5H inductor has a constant current of 2.5A. a) find the energy that it holds b) what is its voltage c) what is its energy after its current drops to zero and stays zero What power is dissipated when a 20 olhm resistor is connected to it
A 4800 bps data transmission device has a bit error rate of 10-6 normally. During a test period, it works at normal conditions except that a 1000ms impulse saturates the channel and all data is lost. Calculate the average bit error rate within the..
Determine the fundamental frequency w0, the period t0, and the coefficients in the representation X(t) = x0 + Re{k=1N Xkejkwot} for the above input. Remember, you can do this problem without evaluating any integrals.
A 500kVA ,7200-240V, 60Hz, transformer with 2.2% impedance was severly damaged as a result of a dead short across secondary terminals. Determine a) The short-circuit current;
