Knowing that a given vertical shear V causes a maximum shearing stress of 75 MPa in the hat-shaped extrusion shown, determine the corresponding shearing stress at
(a) point a,
(b) point b.
An attractive fuel for nuclear fusion is deuterium H 1 2 which constitutes about .015% of the hydrogen in the oceans If each deuterium nucleus produces 7.4 MeV in a fusion reaction, how much energy would be released if each H 1 2 atoms in the 4 gram..
A mealy sequential circuit has one input (x) and one output (z). z can be 1 when the fourth, eighth, twelfth, etc. inputs are present, and z=1 if and only if the most recent input combined with the preceding three inputs was not BCD encoding of a ..
In addition, assume that your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:26) receives the voltage from the high-voltage transmission line.
Find also (c) the bandwidth, (d) the lower and upper half-power frequencies and (e) the value of the circuit impedance at the half-power frequencies.
IN a 2-pole, 208 V (line-to-line, rms), 60-Hz, motor, Rs= 0.5Ω and R'r = 0.45Ω, Xls= 0.6Ω, and X'tr = 0.83Ω. The magnetizing reactance Xm = 28.5Ω. This motor is supplied by its rated voltages. The rated torque is developed at teh slip s = 0.04.
The generator voltage is 120 V and the lamp voltage should be 110 V or more. Calculate the current drawn by each lamp if its voltage is 110 V and its power is 100 W. Calculate the current in the two-wire line. Calculate the maximum resistance of t..
Develop a series 90-30 program that functions a motor forward/reverse controller.. Design your circuit so that the stop push button must be pressed before the motor can switch direction. Also incorporate a 5 second delay to inhibit restart after the ..
Half and Full Wave rectifying and Fourier Rectifying a sinusoidal provides a way to create a dc source. In this problem we consider the Fourier series of the full wave and half wave rectified signals. The full wave rectified signal xf(t) has a per..
Two point charges, Q1 =30 C and Q2 =-100 C,are located at (2,0,5) m and (-1,0,-2) m, respectively. Find the force on Q1 and Q2.
A 25MVA, three phase, 13.5kV, Y-connected, two pole, 60Hz synchronous generator was tested by the open circuit test and short circuit test and tabulated in table 1. If the armature resistance is 0.24 ohms per phase.
A) How far is the spring stretched at the equilibrium postion B) How much potential energy is stored in the spring C) the mass is pulled down a distance of 4.50 cm and released. How fast is the mass moving when it is 2.50 cm above the equilibrium p..
four determinations of the pH of a certain solution are 7.90, 7.94, 7.91, and 7.93. Assuming normallity of determinations with mean mhu, standard deviation sigma, find: A. 99% confidence interval for mhu "u"
