Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. (Retrieved: April 12, 2013 http://en.wikipedia.org/wiki/Polystyrene) Expanded polystyrene beads makes up a Styrofoam. Styrofoam is used almost everywhere: it is used as housings of appliances such as televisions, computers and refrigerators. It is also utilized as drinking cup especially for hot beverages because of its insulating properties. As a student, the most common use of Styrofoam is for artworks and projects. Cutting this brittle and very light substance is one of the hardest parts in its utilization. The researcher thought of a way to improve Styro cutting. The Effectiveness of Improvised Styro-Cutter is a study that focuses on making a Styro-cutter that offers a fast, efficient and precise cut of Styrofoam.
Statement of the Problem
1. What Physics principles are involved in the study?
2. How effective is the Improved Styro-Cutter in terms of: 2.1 Cutting Precision 2.2 Durability 2.3 Economic Value 2.4 Speed and Accuracy
3. What sample products can be created using the Improvised Styro-Cutter?
Hypothesis
1. AC – The electrical energy will be converted to heat energy with the use of a converter. This heat energy will transfer to the guitar string (nichrome, a good conductor) so when the Styrofoam (polystyrene with a melting point of 240) touches the string, it will melt and will eventually cut the Styrofoam to its desired shape. DC - The chemical energy in the dry cell will be converted to heat energy with the use of a converter. This heat energy will transfer to the guitar string (conductor) so when the Styrofoam (polystyrene with a low melting point) touches the string, it will melt and will eventually cut the Styrofoam to its desired shape.
2. The Improvised Styro-Cutter will produce precise cuts. It will also be durable because of the materials to be used. Though the materials used are
