Relationship Between Thermal Conductivity And Free Electrons In Metal, Yansong Liu
Relationship Between Thermal Conductivity And Free Electrons In Metal, Yansong Liu
Senior Theses
An experiment was designed and conducted to explore the relationship between thermal conductivity with free electrons in metal. In the experiment, copper, iron, aluminum, and titanium rods with close diameters were used to carry out the experiment. Each rod was heated up by a heat unit at one end while cooled on the other end with a heat sink to maintain a steady state. DC current was applied to rods in the direction along, as well as against, the heat flow. Thermal conductivities were measured in these two situations for each rod. Results showed electrons do dominate thermal flow inside …
Securing Pint Glasses On Serving Trays With Magnetic Attachments, Jayden Commendatore
Securing Pint Glasses On Serving Trays With Magnetic Attachments, Jayden Commendatore
Senior Theses
It is extremely common for servers in the restaurant industry to have pint glasses slip off their serving tray, wasting both time and money for the restaurant. I have designed a sleeve attachment that will clip on to the bottom of a pint glass. The metal sleeve attachment will be attracted to a magnet placed into the serving tray. This increases the normal force of the pint glass, resulting in an increase in the friction force between the tray and sleeve attachment, and helping secure the glass to the tray. In order to optimize the design, the value of the …
Design Of Smart Trashcan, Haoran Song
Design Of Smart Trashcan, Haoran Song
Senior Theses
A smart trashcan has been designed which can bring convenience to people for throwing their garbage away during the COVID-19 pandemic. A prototype is made from cardboard to demonstrate its function. This trashcan can sense people who are coming and leaving, and it can open and close automatically. The trashcan is powered by solar energy. A solar panel is mounted on top of the trashcan supporter. This design is specifically for use in China.
