A plate of 2-mm thickness is bent as shown and then used as a beam. For a vertical shear of 5 kN, determine the shearing stress at the five points indicated and sketch the shear flow in the cross section.
Design a device that creates a voltage that is a damped oscillation with a frequency of 5 radians per second and a time constant of 3 seconds. In particular, explain how initial conditions are to be handled.
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
The dielectric of a parallel plate capacitor has a permittivity that varies as ero+ax, where x is the distance from one plate. The area of a plate is A, and their spacing is s.
What approximate minimum BER is required for voice signals, data signals and what is the approximate BER level for the optical fiber systems ?
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.
The total friction and core losses may be assumed to be constant at 403 Watts, independent of load. For a slip of 2% , compute the speed, output torque, and power and stator current, power factor and efficiency when the motor is operated at rated ..
RC ciruit= Current course (3u(-t) A) in parrallel to 6k ohm resistor and 5uF cap. Determine the instantaneous power absorbed by the resistor at t=(0); 30ms; and 90ms.
An automobile battery is charged with a constant current of 2 A for five hours. The terminal voltage of the battery is v = 11 + 0.5t V for t > 0, where t is in hours. (a) Find the energy delivered to the battery during the five hours. (b) If electric..
Suppose a tiny particle were to be attached to the string at x = 5 cm, obtain an expression for the vertical velocity of the particle as a function of time.
A storage tank has a Diameter of 20ft and a height of 10ft. The output volumetric flow from this tank is given by fout(t)=2h(t) where h(t) is the height of the liquid in the tank. At a particular time the tank is at steady state with an input flow..
A PN flip-flop has four operations, clear to 0, nochange complement, and set to 1, when inputs P and N are 00,01,10,11 are respectively. a) Tabulate the characteristic table b) Derive the characteristic equation.
Given a DSP system in which a sampling rate of 8000 Hertz is used and the antialiasing filter is a second order Butterworth low pass filter with a cutoff frequency of 3.2 KHz determine a. The percentage of aliasing level at cutoff frequency
