A national laboratory has stated that they are responsible for a ceramic machining program that intends “to provide measurement methods, data, and mechanistic information needed by industry to develop innovative cost-effective methods for machining advanced structural ceramics.” Grinding with diamond wheels is the most prevalent method of machining advanced ceramics. This machining is highly complex and depends on many interdependent factors. The major elements of a grinding system are the grinding wheel, the grinding fluid, the machine tool, and the workpiece. Each of these is associated with several parameters that can influence the grinding process: such as, the type and size of the diamond grit, the properties of the grinding fluid, method of delivery of the grinding fluid, and grinder characteristics (e.g., stiffness and vibration).

A specific experiment is proposed to characterize the effects of grinding parameters on the flexural strength of ceramic “A.” The investigators are particularly interested in the effects of grinding speed, wheel diamond grit size, and “down feed rate” on the ceramic strength.

What is the goal of the lab with respect to machining ceramics and state an objective for the specific experiment
Give an experimental plan. Which factors are varied and the number of levels. How you might determine the values for the levels for each factor? What are the advantages and disadvantages of this plan?
Three other variables not described anywhere in this problem description that may not be simple to control? For each variable, what might be done to avoid confounding the experiment due to these variables?
The need for replications that is specific to this type of experiment?

Assume that engineers at a national research laboratory built a prototype automobile that could be driven 50 miles on a single gallon of water as fuel. They estimate that in mass production the car would cost $100,000 per unit to build. The engineers argue that Congress should force U.S. automakers to build this energy-efficient car. In your opinion, is energy efficiency the same thing as economic efficiency? Please explain your opinion and state whether you support it or not. Please...

Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal distribution, and the three times are independent of one another. The mean values are 15, 20, and 30 min, respectively, and the standard deviations are 2, 1, and 1.7 min, respectively. What is the probability that it takes at most 1 hour of machining time to produce a randomly selected component? (Round your answer to four decimal places.)
