Question: Solve Example using
(1) two elements and
(2) eight elements. Compare your results to the exact values
Example: Consider a bar with a variable cross section supporting a load P, as shown in Figure. The bar is fixed at one end and carries the load Pat the other end. Let us designate the width of the bar at the top by the bottom by , its thickness by r, and its length by L. The bars modulus of elasticity will be denoted by E. We are interested in deter-mining how much the bar will deflect at various points along its length when it is subjected to the load P. We will neglect the weight of the bar in the following analysis. Assuming that the applied load is considerably larger than the weight of the bar
A commutator motor with its armature supplied from variable voltage source. As the voltage is varied from 0 to 600V,the drive speed varies from 0 to 1600rpm, the field flux isconstant, all losses-ignored.
If at another time the engineer changes the power input linearly at a rate of 0.5 kW/min, what can you say about the maximum rate of change process temperature. When will it occur? How large will it be?
A long hallway has three doors, one at each end and one in the middle. A switch is located at each door to operate the incandescent lights along the hallway. Label the switches A, B, and C.
A pulse is used to measure the frequency response of a system. Since we expect the frequency response to extend to 20 kHz, select a pulse whose magnitude spectrum is constant within 1% out to 20 kHz.
Fortunately, for this purpose, we can replace multiplication with switching operation. A similar observation applies to demodulators. In the scheme depicted in fig p7-40a, the period of the rectangular periodic pulse x(t) shown in Fig. P7-40b is T..
Carry out the preliminary design of a closed domestic hot water heater that has a first law efficiency of at least 95.0% and a second law efficiency of at least 10.0%.
Extend the approach illustrated in Figure to a cascade of a second-order system and a first-order system. Determine the logical operation of the output combiner.

A variable-frequency voltage source of value 12cos(wt) drives a network with a resistor of value 12 ohms, an inductor of value 50mH, and a capacitor of value 5uF, all in series, in that order.
How hot would a conventional pipe have to get to burst and why. Does it vary according to what material the pipe is made of. Which are the strongest. What are weak ones
Consider four logical input lines(A,B,C, and D) to represent a fourbit decimal integer. The decimal value of this four bitinteger is to be shown on a seven segment display. You are todesign a function to turn on one segment of the display.
