 ==Executive Summary==
-The objective of this guided investigation was for our group, Group 24, to look into the assembly, function, manufacturing, and materials of the [http://en.wikipedia.org/wiki/PlayStation_2 PlayStation 2] gaming console via analytical dissection. The PlayStation 2 is a popular gaming console meant for the household. The group carefully recorded the investigation: we did a visual pre-dissection analysis, dissected the product and then reassembled it. Our pre-dissection analysis consisted of taking pictures of the PS2 we received and guessing as to the nature of the operation of the console, all the while recording our observations; since the console was not functional when we received it we continued on to the dissection. The disassembly was fast and easy due to the group taking a methodological and efficient approach to the task: we took pictures of each step, organized loose parts and made a written record of each step. During the dissection we paid close attention to the connections between the components and how they interact with each other. Post-disassembly consisted of the group investigating each part individually to uncover its function. Because of the cataloging of part and methodological dissection the reassembly was very easy and fast, involving little to no difficulty.

		+	===Reasoning for Materials Used for Parts===
		+	Record why your group thinks each component was made out of its type of material
		+	*Screws made of metal (steel) because they need to be able to hold the PS2 together, even under stress, with little warping or bending so that they can be easily unscrewed
		+	*Gearing is plastic because it is cheap and easily moldable into a gear shape, metal gears would be more expensive and can withstand way more stress then necessary for a CD-ROM
		+	*Belts in the optical are rubber so that they can easily bend to transfer power between motors and the CD tray
		+	*Heatsink must be metal because metal has a low enough specific heat that it can easily draw heat from the CPU/GPU
		+	*fan must is plastic because it is easy to mold plastic into the blade shapes and a metal fan could be a hazard

 ===Purpose===
-The Sony PlayStation 2 gaming console is a video gaming entertainment console for the home. The main purpose of the PS2 is to provide the user with an interactive arcade-style experience in the comfort of their home at a lump sum cost, rather then the continuous spending that would be associated with arcade playing. The PS2 works by reading game data from an optical disk, converting this read only memory to functional RAM and then processing this game information in a GPU (graphics processing unit). The RAM, GPU information and any input from the user via the PS2 game controller are then processed in what is called an “Emotion” Engine. The Emotion Engine assimilates all the information from the 3 system processes into what you see on the screen. This whole process is the only computational part of the PS2, all other processes are “support” processes. Because the electrical components in the parts of the PS2 generate heat due to their naturally electrical resistivity, the heat sink must dissipate the heat from the CPU/GPU and then the internal fan must circulate this hot air to the outside, so that the cooling can occur continuously and keep the electrical components at a temperature low enough so that they function at optimal performance levels.

 ===Energy Usage and Conversion===
-Many types of energy are used and converted in the PS2: This all starts with the mechanical energy the user provides to complete the power on circuit. This circuit now allows the electrical current from the wall socket to permeate the electrical components of the system.
+Many types of energy are used and converted in the PS2: This all starts with the mechanical energy the user provides to complete the power-on circuit. This circuit now allows the electrical current from the wall socket to permeate the electrical components of the system.
 	The electrical energy is converted into:
-*In the CPU the electrical energy is transmitted to the transistors to perform logical operations and as a result of the resistive nature of the components of the CPU, partially transformed into (useless) heat energy
+*In the CPU the electrical energy is transmitted to the transistors to perform logical operations and as a result of the resistive nature of the components of the CPU, the electrical energy is partially transformed into (useless) heat energy
 *The fan converts the electrical energy into magnetic energy in its motor which is converted into rotational energy to dissipate the heat from the heat sink to the environment (a temperature low reservoir)
-*The CD-ROM reader converts the electrical energy to magnetic energy which is converted to rotational energy to spin the CD-ROM so that is can be read by the LASER head, which converts electrical energy to magnetic energy which is converted to rotational energy which is converted to kinetic energy which moved the head on its slides, the head also converts some of the electrical energy to light energy for its laser, when the laser bounces off the CD-ROM it is converted back to electrical impulses which are read as data by the processor
+*The optical reader converts the electrical energy to magnetic energy; this energy is used spin the optical disk by way of a motor (rotational energy). LASER head then reads the disk. The LASER head uses several types of energy: energy to move the head on its slides and energy for the motor to spin the gears to move it. The rest of the electric energy to the LASER is used as light energy for its laser. When the laser bounces off the optical disk it is converted back to electrical impulses which are read as data by the processor
 *The mechanical energy the user transfers to the controller via the buttons is converted into electrical impulses which are transferred to the CPU for analysis
