You are to present your idea to the engineering committee which is to decide whether a full scale engineering study of this design is to be undertaken. You need to develop the case for this design, including what temperature T for the lithium tank produces the greatest efficiency for this two-engine solution and how does this efficiency compare to the standard design.
(3) Your friend, an artist, has been thinking about an interesting way to display a new wind sculpture she has just created. In order to create an aural as well as visual effect, she would like to use the wires to hang the sculpture as sort of a string instrument. Her basic design involves vertically hanging two pieces of wire from two eye hooks on the ceiling that are approximately then hanging the heavy sculpture from a horizontal bar from some point along the bar. The aural effect that she would like to achieve is that when the wind blows across two vertical strings, they play a perfect fifth, i.e., the ratio of the frequencies of the two sounds is 3:2. Your friend tells you that she has been successful in hanging the sculpture but not in choosing the point along the bar to hang the sculpture giving the desired sound. Desperate for success, she knows you are taking physics and asks you for help.
What is your advice concerning the design of the sculpture. What notes will the two strings play with your design?
