Applied Mechanics/ Structures & Mechanisms/ Manufacturing
Objectives/Goals I like playing golf and often wondered why the length of a club affects the distance the ball travels. It feels like the longer clubs just have more power when I swing them!…

Applied Mechanics/ Structures & Mechanisms/ Manufacturing
Objectives/Goals My project was to find out if there were any disadvantages to using pulleys to lift weight. I think when you use more pulleys it gets easier to lift a certain amount of weig…

Applied Mechanics/ Structures & Mechanisms/ Manufacturing
Objectives/Goals My project was to evaluate how different sling lengths and counterweight masses affect the distance a trebuchet throws a ball. My hypothesis was that a trebuchet would shoot…

Applied Mechanics/ Structures & Mechanisms/ Manufacturing
Objectives/Goals To determine which lubricant has the least friction. Methods/Materials First, I bought a long strip of sheet metal then cut it into a rectangle. Another metal sheet was cut…
CSEF · 2005
Applied Mechanics/ Structures & Mechanisms/ Manufacturing
Objectives/Goals To first build a reproduction of an 1883 Wimshurst Influence Machine that would produce static electricity without the use of friction. Secondly, to improve on the design of…
