Textbook Question
Chapter 7, Problem 7.3P
You serve as the president of XYZ corporation, which is an energy intensive manufacturing operation. You have four boilers to produce steam and electricity for your operations. One is a semi-suspension fired boiler with a capacity of 100 tons of coal per hour. The boiler can also burn supplemental fuel such as coconut or macadamia nut shells. The other three boilers arc peaking units and burn fuel oil. The City of Podunk has approached you about the possibility of burning solid waste as a supplemental fuel. As the president of the XYZ Corporation, you need to develop answers to many political, social, and technical questions before you make a commitment to the city.
a. What specific questions would you ask your own power plant engineer about the possibility of accepting Podunk’s MSW?
b. What specific additional data would you need from the city
before you discuss this further?

(b) Generate a 3D surface plot and contour plot of the joint PDF fxx, (x,x) using Matlab or any other
software of your choice.
(c) What is the standard deviation of X2?
(d) Construct a transformation from the physical X space (defined by random variables X, and X,) to the
standard normal U space (defined by the statistically independent standard normal random variables

b. Determine the equations of the slope and the elastic curve using the coordinate x.
First, solve this problem parametrically, and then substitute the numerical
values for L, E, I, w at the end. There will be a significant penalty for solutions
that do not calculate the slope and deflection as parametric functions.
c. Specify the slope (in radians) at point A (parametrically and numerically).
d. Specify the vertical displacement at point B (parametrically and numerically).
