Your answers and
figures should be made with a word processing and drawing tool (Paint). Please
submit a hard copy. Electronic copy will be accepted if sent as text and bitmap
files, do not send “wps”
files.
The following problems are for you to practice problem solving and idea
generation. These designs should pass the “conceptual test”, i.e., after seeing
the drawings, the reader can agree that prototypes based on these designs will work.
A good design should be able to solve at least one anticipated problem.
1.- Provide a design of a mechanism to lift something using a force which is half or less its weight. Detailed drawings that illustrate the concepts are essential. Anticipate one possible practical problem and provide a second design (based on the first one, or completely different) that overcomes the problem.
2.- Provide a design of a human prosthetic arm, it should be able to fold and swing by the elbow. Detailed drawings that illustrate the concepts are essential. Anticipate one possible practical problem and provide a second design (based on the first one, or completely different) that overcomes the problem.
3.- You are given an egg, some tape, and several drinking straws. Using only these materials, design a system that will prevent the egg from crashing when dropped from a height of six feet (two meters). Detailed drawings that illustrate the concepts are essential. Explain what natural element or phenomena you are trying to use to your advantage.
4.- You’re in the Block Diagram window inside LabVIEW, wiring an operator and a string indicator. You’ve wired circuits before and they worked, so you are an experienced ‘wirer’, but this time you always get a broken wire. What could have happened and how do you fix the problem?
5.- You’re having a broken Run Button, tell two ways to get the error list
6.- Tell how would you assign the connectors of a newly designed subVI.
