The table below gives the three elastic moduli for several materials. According to (16.100) Young's modulus for any given material can be calculated if we know the bulk and shear moduli. Using the data for BM and SM, calculate YM for each of the materials and compare with the given values in the third column. (The densities will be needed for Problem 16.32.)
Problem 16.32
[Computer] Using appropriate software, calculate the speeds of longitudinal and transverse waves in the five materials listed in Problem 16.26. Arrange for the software to give you a nice readable table of values.
MATLAB to design a compensator to meet the specifications - Feedback system has an open-loop transfer function
a) Plot the spectrum and the normalized spectrum of x[nT] = 2cos(20*pi*n*T + pi/8) + 4cos(40*pi*n*T + pi/8) for T = 0.01 b) Plot the spectrum and the normalized spectrum of
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
The customer forgot to tell you that they need the bias (0V at 00000) to be user-adjustable between 0V and 2V and that the range(5V between 000000 and 111111) must be user adjustable between 3V and 7V.
A pn junction diode has Vd= 690 mv, C=6pF, Id= 500 microamps, Vt=.0259 V. It also has C=4pF when Id= 100 microamps. Derive the complete high-frequency model when Vd=610mV.
Design a 2-digit 24 second "shot-clock" countdown timer with pushbutton controller.
a) Find the intersection of the two lines. b) Find two vectors that also describe the two lines originating from the intersection. c) Find the angle between the two lines.
An analog signal xa(t), band-limited to 5 Hz, is sampled at a rate of 10 samples per second to give a discrete-time signal x(n) = xa(0.1n). The discrete-time signal x(n) is then filtered with an digital FIR filter, h.
the donor energy level is approximately 0.1 ev below the conduction band. the approximate value is calculated from the binding energy equation from hydrogen. derive the binding or ionization energy which is equal to the total energy.
A cylindrical specimen of cold-worked steel has a Brinell hardness of 250.
The signal generator have many options for generating different wave forms. It also have BMC connector labeled as "OUTPUT50 ohm" 1) What does the 50 ohm label on the output terminal mean
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
