1. What are the three important technical dimensions of lubrication oil analysis?
2. Define Total Acid Number (TAN) and Total Base Number (TBN) of lubrication oil and state their importance in machinery lubrication (this may require internet search).
3. An ultrasonic beam travels through an 8-inch thick carbon steel plate and strikes a body of water. The following data for carbon steel and water are given.
Density of carbon steel = 7.85 gm/cm3
Density of water = 1 gm/cm3
Longitudinal velocity of sound in carbon steel = 0.594 cm/µ sec
Longitudinal velocity of sound in water = 0.149 cm/µ sec
(a) Calculate the acoustic impedances of carbon steel and water. Indicate units.
(b) Calculate the percent of ultrasonic wave energy reflected.
(c) Calculate the percent of ultrasonic wave energy transmitted.
Show a block diagram similar to Fig. for the data transfer from a CPU to an interface and then to an 1/0 device. Determine a procedure for setting.
Beginning with the multiply-ordered linked list of names and id numbers pictured in the text, show the linked list that results from each of the operations.
Understand and apply reliability concepts and terminology - Understand and apply the basic mathematics involved in reliability engineering.
Create an up/down counter that is able to increment the display going from 0 to f (or f to 0) and then back around every clock cycle.
A continuous time function is shown below in figure 1. This signal is a sinc function defined as y(t) = sinc(t). The Fourier transform of this signal is a rectangle function.
Figure shows a circuit suitable for op-amp applications. For all transistors β = 100, VBE = 0.7 V, and ro =∞. For inputs grounded and output held at 0 V (by negative feedback) find the collector currents of all transistors. Neglect base currents.
It is stated that multiprogramming and multiprocessing present the same problems, with respect to concurrency. This is true as far as it goes. However, cite two differences in terms of concurrency between multiprogramming and multiprocessing.

Project - EET-540 Energy Management System and Smart Grid. Draw the flowchart of the optimal Energy Management System
If p is in fact less than 0.301, would it make you suspect that there are not enough numbers in the data file with leading 1's? Could this indicate that the books have been "cooked" by "pumping up" or inflating the numbers?
A thin, homogeneous bar having a mass of M and length L is pinned to ground at its mass center G. Particle B, having a mass of m, is rigidly attached to the right end of the bar. When the bar is horizontal (Position 1 shown below), the spring is uns..
