At the beginning of this assignment, both McKenna and I had no idea how to build a bottle rocket. After visiting several websites and researching multiple ways of making it, we settled on a single bottle rocket with a rounded nose cone and three fins. This was chosen because it was the easiest model to create and that meant a less likely chance of messing up. We were just concerned with getting the rocket into the air. The rounded nose cone was created by layering paper and then rolling it and folding it in way that fit around the bottle and was not a completely pointed cone. We then layered it with duct tape to keep it somewhat stable. Before attaching it to the bottle, we put five fishing weights in the top and then stuffed the remaining space with paper. After that, an outrageous amount of duct tape was used to put the nose cone in place. Following that we started to work on the fins. There were two different fin shapes that we tried. The first was a long skinny triangle. The second type was a rather wide triangle with two of the corners chopped off a bit. Each of them was cut out of cardboard and was then covered in duct tape in order to keep the cardboard from getting wet and …show more content…
falling apart. Each bottle rocket had three fins which were attached with hot glue and later with duct tape and hot glue. On Monday we had the rockets finished and decided to do some test launches.
The first bottle rocket we launched was the pink one that had the wider fins that had two cut off corners. The launch went way better expected, it actually got off the ground and went relatively high with a decent flight time. The landing did not go as well. In the process of hitting the ground, our rocket lost one of its wings. To fix this the first time we simply applied more hot glue, but this warped the bottle even more. The second bottle rocket we launched was the blue one with thin triangular fins. Both the launch and landing were embarrassing. The rocket didn’t make it very high and only stayed in the air for a second or two. Upon impact, all three fins fell off. We also reattached the fins with hot
glue. On Tuesday we launched the pink one twice for both height and flight time. The first launch, which was for height, did not go as well as expected. The bottle rocket did not go as high as it did on Monday. It only was at 17.3°. Once it hit the ground, one of the fins fell off. McKenna and I went inside to fix it with both duct tape and hot glue. The second launch went pretty well. The flight time was pretty decent at about a little over six seconds at 6.23 seconds. Once the rocket hit the ground after that launch, the two fins that were not reinforced earlier fell off. In order to fix this, we secured them with both duct tape and hot glue. On Wednesday we again launched for height and flight time. First we launched for height. This time it went a lot higher and reached 30°. This was a difference of 12.7°, a huge improvement. Happily the fins all stayed on. The second launch we did was for flight time. For this one we shot the blue rocket with the thin triangles. Unfortunately the time did not beat our last one of 6.23 seconds. Surprisingly these wings didn’t fall off either. During the project, the biggest obstacle we had to overcome was not knowing anything about bottle rockets. This entire project was a guess and check and take advice from others type process. We also kept having wings fall off. Each time we had to come up with different ways to fix it. In the end, both bottle rockets turned out better than expected (they got off the ground and didn’t explode) and it was a lot of fun.
PAINFUL HEMORRHOIDS - What are the HEMO Fast and long-lasting RELIEF for both internal and/or external hemorrhoids! The “Rectal Rocket” suppository is designed to treat hemorrhoids in 3 days or less**. It is more effective than a traditional suppository because of its unique design and comfortable fit. It remains positioned for many hours to soothe and treat the enlarged and swollen tissue without getting lost in the rectum. The contoured top portion of the suppository is inserted into the rectum and treats internal hemorrhoids, while the larger flared base of the suppository remains on the outer surface of the anus to treat external hemorrhoids.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
Design the turtle brought up ever before seen challenges. You could not use candle for light as the flame will use up air. Designers need to find way to move on all 3 axis. Lastly and most importantly it had to be airtight. There were unique solutions that to us now seem obvious. To solve the light issue a type of wood fungus called fox fire, this created its own issue in that if it fisted over it would stop working meaning that the mission would have to go forth in summer. To move on all the axis the torte had 3 impellers, one on top and 1 on either side. The craft also had a rudder. Moving up and down was achieved by having a tank in the bottom that could be flooded with water to sink and pump water out to rise meaning that you can change the amount of weight. Making a watercraft was basically done by building something that they already knew would hold water a barrel, essentially the turtle was a large barrel. Another design element was the lead keel that kept the craft upright.
The calculated hurdle rate includes a safety margin because the highest measure of Re is used. This is not to say that Re could never succeed .
According to Miller, Ron. The History of Rockets. N.p.: Grolier, 1999. Print. "The forces of action and reaction, which propel the rocket forward, occur the moment the fuel is burned-before the exhaust leaves the engine." (Miller 10). the combustion within the motor is burning the fuel (reactants) causing the exhaust (products) to leave the motor pushing the rocket up.

Experiment to Find Out Which Fuel Produces Most Energy. Aim = == My objective in this piece of coursework is to determine which of five fuels produces the most energy and if the energy production relates to the amount of carbon..
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
In the book Rocket Boys, there were many themes throughout the book, such as coming of age, determination, dreams / goals, family relationships, and man vs. society. I think the most relevant theme of all was determination. Determination can be one of the best things for someone, but also one of the most dangerous things for a person to have. If someone is determined about something to happen, they can and will make it happen no matter the circumstance. This can become a bad thing if someone is determined for the wrong reason or is determined for something to happen to someone or have something bad happen. Determination is the amount of drive someone has to get something done. If someone is extremely determined to get something done or to have something happen,
Overall, Rocket Boys had a constant repeat of the boy's dreams and goals. I think these dreams and goals were very important to the boys, and hope, encouragement, and admiration helped the boys reach their

In order for any rocket to fly, it must obey some basic rules of physics. No rocket can escape the cardinal rule that the center of gravity must be in front of the center of pressure.
Is it ethical or even helpful to try to impose order on a haphazard existence? Is it right to play God, to steal the limelight from the cosmos? Man used to ponder existence, but with the increasing possibilities of science, we now ponder our power over existence. In “An Experiment with an Air Pump,” Shelagh Stephenson uses symbolism associated with Isobel as a voice of foreboding in a society “enraptured by the possibilities of science” (3). Stephenson associates Isobel with a bird, a pile of bones, and a sheep to reveal the dark side of the “light,” the scientific revolution.

Projectile motion is used in our daily lives, from war, to the path of the water in the water fountain, to sports. When using a water fountain or hose, projectile motion can be used to describe the path and motion of the water. This technology was created by finding the angle at which the water would come out at a maximum height and the person using it would be able to drink it without leaning over too much. These types of projectile motion will be further explored and analyzed in this assessment.
