CW 2

(Class Work #2)

1) Why do we have cycles in engineering design? Draw a flow chart with four most important steps in an engineering design cycle.

2) Draw a flow chart for an in-out system. Label the input and output variables as X and Y, respectively, and explain what are they for at least two simple systems based on gravity. Given a value for an input X, is it possible to determine exactly the value of the output, yes or no, explain why.

In each team, students working together at a computer numbered between 1 and 10 will submit file cw2_XX_a.html and folder cw2_XX_a_files, students working at a computer numbered between 11 and 20 will submit file cw2_XX_b.html and folder cw2_XX_b_files, to the files folder in the server. Replace XX by 01 if team 1, etc. Include your names within the files.
