Performance data for an experimental truck engine were recorded in a recent laboratory test as shown in the table below:
 FIGURE 1.png)
As a team
(a) Plot each data set on linear, semilog, and log-log graph paper with engine speed as the independent variable.
(b) Using the method of selected points, compute the best equation fit to these data.
(c) Repeat parts (a) and (b) using computer-assisted methods.
(d) Discuss your results in a form that could be understood by other engineering students who have not solved this problem.
Hint: For data that plot as a convex upward curve, try reversing the independent and dependent variables in a plot before applying a curve fitting method. Once the equation has been found, simply solve for the desired dependent variable as a function of the independent variable.
