A torque T = 750 kN.m is applied to the hollow shaft shown that has a uniform 8-mm wall thickness. Neglecting the effect of stress concentrations, determine the shearing stress at points a and b.
Problem 1: In the figure shown, each resistor has the same resistance R. The equivalent resistance measured between terminals A and B is Req = 38 Ohms. Determine the value of R.
Fnd the attenuation provided at ω=2ωp by aseventh-order Chebyshev filter with a 0.5dB passband ripple. If the passband ripple is allowed in to increase to 1dB, how much does the stop band attenuation increase.
the voltage across an element is 12e^-2t V. the current entering the positive terminal of the element is 2e^-2t A. Find the energy absorbed by the element in 1.5 seconds starting from t =0.
Design each of the circuits specified in the Procedure section of this lab. Your design should attempt to get within § 5 % of the specified gain. All designs are to use standardcommercial 5 % resistors. You may only use a single resistor for each ..
assuming k>0 what is steady state the response of the above system due to an input of the form , x(t) = 2sigma(t)+u(t). where sigma(t) denotes unit impulse function and u(t) denotes unit step function
A cloud company has 20 computers total. Out of the 20 computers, 9 run web servers and 12 host databases. Furthermore, 8 machines offer file sharing. Note that a particular machine can offer multiple services.
Consider the step responses of two different imaging systems, one with a circular aperture of diameter 2ω and the second with a square aperture of width 2ω, with one edge of the aperture parallel with the edge of the step.
A signal x[n] is formed by sampling a signal x(t) = -4sin(200*pi*t) at a sampling rate of 400Hz. Graph x[n] over 10 fundamental periods versus discrete time. Then do the same for the sampling frequencies of 60 and 200Hz.
The air feels humid. No air is coming from the registers. The air handler is in the attic. An examination of the condensing unit shows that the suction line has ice all the way back to the compressor. The compressoris still running.
Consider a cellular phone transmits data using QPSK with achannel rate of 50 Kbps, (a) what is the data rate provided (b)What is the difference between PSK and QPSK.
PLC 2 In a motor control system, one master stop pushbutton (Stop) is available for stopping the operation at any time. If the temperature switch (TSW) is closed, pressing the red pushbutton (RedPB) will turn on both motors M1 and M2.
a conductor is connected to a battery and placed between two compasses. An electric current is then passed through the conductor. In what direction do the poles of the compasses point.
