A rectangular plastic specimen of size 100 X 100 X 10 mm3 is placed in a rectangular metal cavity. The dimensions of the cavity are 101 X 101 X 9 mm3.
The plastic is compressed by a rigid punch until it is completely inside the cavity. Due to the Poisson's effect, the plastic also expands in the x- and y-directions and fills the cavity.
Calculate all stress and strain components and the force exerted by the punch.
Assume that there is no friction between all contacting surfaces. The metal cavity is rigid. Elastic constants of the plastic are E = 10 GPa and ν = 0.3.
Using a 1-mA, 100-Ω d'Arsonval movement, design a multirange voltmeter having scales of 5 V, 50 V, and 500 V.- Show the circuit and component values.
Design and simulate a power supply that takes line voltage(120v) and produces a 15V output with less than .5% ripple voltage with the following specifications use either full wave or full bridge wave.
question 1consider two digital sequenceshere m is a positive integer and is a value in the intervala using the
A 480V, 60 Hz three phase induction motor has the following parameters: R1=R' 2= .3 ohms Xeq= 1 ohm Xc=600 ohms At full load, the motor speed is 1120 rpm, the rotational loss is 400W and the core loss is 1 kW.
Design (determine) the metallurgical channel thickness of an n-channel silicon JFET such that the pinch off voltage is -3.0V. The doping parameters are NA=3x1018cm-3 and Nd=2x101616 cm-3.
Estimate this value, mod(2π), using the linear model. How do they compare? Repeat for λ = 0, λ = 0.05, and λ = 0.2. What do you conclude?
When the temperature is held constant, the digital display of thermometer A does not change, but the display of thermometer B randomly toggles between three to four adjacent readings (i.e., +/- 2 degrees). For the questions below, assume that the ..
2a.) Find A dot B if A = 3e1+ 5e2-e3 and B = e1 -e2+ e3 if e1 dot e1 = 2, e2 dot e2 = 3, e3 dot e3 = 5, e1 dot e2 = -1, e1 dot e3 = -3, e2 dot e3 = 2
A motor with efficiency of 76% supplies 20 hp to a load. it's power factor is 0.6 (lagging). A voltage of 440 VAC (RMS), 60 hz is applied to the motor a) what is the real power applied to the motor in Watt
Find the time required for vC to reach 60 V following the closing of the switch. - Calculate the current iC at the instant vC = 60 V.
Suppose we measure the noise in a resistor (with no applied voltage) and find that the noise voltage exceeds 10 μV 5% of the time.
The initial voltage across the capacitor shown in Figure is vC(0+) = 10V. Find an expression for the voltage across the capacitor as a function of time. Also, determine the time t0 at which the voltage crosses zero.
