Reverse Engineering Project
The major problem my group tried solving was the difficulty many musicians have when performing and having to flip their music sheets by hand. To fix this, my group decided to take a music stand and make it more efficient by it having an automatic page turner that would be activated when someone stepped on the pedal at the bottom of the stand. To make this possible we were going to use a potentiometer that would either be on a timer so it functions automatically or manually. Although we didn´t actually build our modified version due to time, my group still completed all the other steps needed in our reverse engineering project. Because everyone in my group but me is in music, we were able to acquire the necessary resource needed (music stand). First, I disassembled the entire music stand till it was just a bunch of pieces. While I was doing this, the rest of my group was sketching each individual piece and describing its function, as well as drawing the exploded view of the entire stand. All four of us then divided up the work evenly and chose to write an analysis on either the materials, function, structural, or manufacturing. After completing our analysis, we wrote the rest of our report describing our hypothesis and new product redesign, along with finishing our presentation.
Our final product (which wasn´t actually made) was a model #49 music stand that my group made more efficient by it having an automatic page turner activated by a foot pedal, along with a built in light for better clarity. The Manhasset music stand model our group acquired has a unique double desk construction that contributes easily accessible music storage. The vertical extension and desk dimensions of our groups model are identical to a standard symphony music stand. My group finished the teardown of the stand and all other research needed for this project, but we still did not have time or resources at the moment to reassemble and make our modified product.

Content:
Potentiometer- a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. My group would have used this mechanism to turn the music sheet pages.
Voltage- an electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The difference in electric potential between two points in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. My group needed a 9-voltage battery in order to operate the potentiometer.
Axle- a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. Our music stand had an axle between the head and foot part of the stand, which was made to keep the heavy top part stable at all times.
Solid brass bearings- a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The simplest form of bearing, the plain bearing consists of a shaft rotating in a hole. Our music stand was made of all aluminum with solid brass bearings to keep the stand steady.
Music stand shaft- made of all chrome that connects the head of the music stand and the foot that allows the stand to stay standing. The chrome shaft can also controls the various different heights the music stand can reach.
Aluminum sleeve- a small aluminum part that is crimped with a swage tool to create a permanent joint in a wire rope assembly. The aluminum sleeve is part of how the large aluminum top of the stand is manufactured and molded.
