hi everyone!!! In this page, I will be documenting my team's project development. 1. Our team's Chemical Device The objective of our team's chemical device is to stop the accumulation of carbon monoxide (CO) in houses, and help vent out the toxic gas before it reaches a lethal level. In rural areas of Vietnam, people still make use of traditional fireplaces, and if they burn charcoal or wood in an area without proper ventilation, it can lead to the accumulation of carbon monoxide, which is deadly if it reaches too high of a concentration. My team's chemical device is a CO detecting system that is linked to a ventilation system. When the CO detector detects carbon monoxide in a high concentration, it will produce a signal that turns a red LED on, which also turns on a fan to vent out the air, as well as turning a gear that opens a window to let even more air out, thus stopping the accumulation of the carbon monoxide gas. The signal will also produce a loud buzzer noise t...

  Data collected for FULL factorial design using CATAPULT A  Person B: (Thor) Thor will use will use Run #2 and Run#4. To determine the effect of projectile weight. Factor A: Arm Length  Factor B: Projectile Weight  Factor C: Stop Angle  The QUESTION To determine the effect of stop angle on the flying distance of the projectile Scope of the test The human factor is assumed to be negligible. Therefore different user will not have any effect on the flying distance of projectile.   Flying distance for catapult is collected using the factors below: Arm length =   33  cm Projectile weight = 0.86 grams and 2.0 grams Stop angle = 90 degrees   Step 1: State the statistical Hypotheses: State the null hypothesis (H 0 ): Using the  lighter projectile weight from Run #2 and the heavier projectile weight from Run #4 would result in the same di...
