Knowing that for the extruded beam shown the allowable stress is 120 MPa in tension and 150 MPa in compression, determine the largest couple M that can be applied.
On the other hand, when S is high,we should have O1 = I2 and O2 =I1. Thus, S acts as the control input for a reversingswitch. Use Karnaugh maps to obtain a minimal SOP(sum ofproduct) design. Draw the circuit.
A 3-phase induction motor, the equivalent rotor stand still reactance is equal to the reactance, while each resistance is (1/3)rd of this value. A torque of 500 Nmis developed at a slip of 5%. Calculate the maximum torque and thestarting torque.
(a) Calculate the transformation matrix used to rotate an image by 45o clockwise about the Zaxis. (b) How would you use this transformation matrix to achieve the desired rotation (c) Use the transformation matrix to rotate the image point (x,y) = (0,..
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
It is operating at 50% of its rated load at a power factor of .5 leading, compute efficiency using both exact and approximate equivalent circuits as referred to the primary side. Tabulate the percent errors in the currents, voltages, powers
Capacitance can be altered by bringing the two wire line close to ground. (a) Apply the method of images to determine the Capacitance of the two-wire line shown in the figure, where the lower wire is suspended a distance from the PEC ground.
a) How long does it take for the soprano's voice to reach the listener b)In the same time interval, how far form the soprano has the sound wave in the auditorium traveled. Take the speed of sound to be 340 m/s.
Besides being more expensive. How are current limiting fuse different from non-current limiting fuses?
Design a 16 bit x 16 bit combinatorial multiplier. Use a topology similar to the 4x4 multiplier.
A production plant needs a counter that will count 4,000 items before resetting and recycling. How many flip-flop stages would this counter require
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
An optical communication system employs a photodetector whose output is modeled as a Poisson(λ ) random variable X. Find the second moment and the variance of X.
