ndividual Report In this project, a boat had to be made out of foam, a motor, and a propeller along with other chosen materials such as Popsicle sticks and hot glue. The goal of this project was to have the boat go straight and make it to the end of the tub that is about two point four meters in five seconds or less. A partnership of two was formed for this project, and had to test different variables to improve speed and direction, and calculate velocity, buoyancy, and efficiency. The variables that were tested were Rutters, weight distribution, and the boat shape to see what can get the best results on the final test. The boats direction and straightness was tested if having a Rutter helped more than not having a Rutter. The object of the Rutter that was tested was the bottom of a Popsicle stick, approximately one and a half inches long. It was found the adding a Rutter at the bottom of the …show more content…

The boat was tested to see if the shape of the two foam sides of the boat would help increase the buoyancy. Our first test was the two foam blocks with the dimensions of two by ten inches, and cut at a slant in the front, creating a ski tip effect. It was then tested to see if cutting the bottom of the block into a triangle pointed shape would improve the speed and buoyancy, and produce better results than the previous tests. It was observed that the pointed foam blocks did increase the performance of the boat, due to the ability of the point to cut through the water easier, once again decreasing buoyancy. The width of the boat was also decreased and shortened by two and a half more inches to reduce mass and weight, also improving the performance of the boat. After alternating the shape, the length was still at ten inches, but the width was reduced to about four and a half inches. These measurements proved to be our best run, resulting the boat going the whole distance of two point four meters in only four

Shifa Sayeed can you check if this is all in past tense and if it has personal pronouns? The purpose of this experiment was to observe and thoroughly analyze how different substances of dissimilar intermolecular forces acted in different scenarios of evaporation, evaporative cooling, and boiling. In the lab, the three substances tested and compared were Acetone, Acetic Acid, and Propanol.

I have reviewed and read the article carefully. 4. Jim Sullivan’s article “The Mother of All Parbuckles” argues that modern technology parbuckling applies to a centuries-old technique that raised the 2012 luxury liner Costa Concordia in mid-2014, from the ocean bay. In January 2012, the Costa Concordia ran aground in a marine reserve off Italy’s Giglio Island; killing 32 people at the process. Settling on its starboard side on two undersea rock ledges.

The purpose of this experiment was to discover how the flexibility of a hockey stick impacts the distance and velocity at which the puck will travel. If the puck traveled the farthest distance and maintained the greatest velocity then, the puck was launched by the stick with the most flexibility because it was able to generate more force to launch the puck. However, when testing out just the flexibility of the stick alone, it was puzzling to find that the Bauer Vapor x60 Composite Stick was capable of firing the puck a greater distance and at a greater velocity than the Easton 53 Composite Stick. There had to be another factor that was being missed. It was determined that the flexibility of a hockey stick is not the only factor that impacts the distance and velocity of the puck.

Each oarsman must time every individual stroke perfectly, or a series of unfortunate events will follow; the boat may begin to turn, the boat can rock from each rower slamming his oar into the water at different times, or a rower can catch a crab, which is to hit the water after everyone else and immediately slow the entire boat down. Perfect synchronicity is key to the composure of the

We followed this rule to avoid being disqualified which would have made people upset and annoyed which could have caused fights and emotional trauma between friends and our class. It also meant we didn’t have a lot of people on the water which would increase the chances of people being injured. This would have happened because it would mean there would be a larger number of people in the same amount of space giving people less space to move causing them to trip or accidentally kick somebody. The outcome of our class doing this was overall positive. This was because nobody got injured and everybody had fun while building the raft and during the racing of

Ever since its incipience, the boat has been one of the greatest inventions to ever aid humanity. Two civilizations that were known for their nautical excellence were the Byzantine Empire in Eastern Europe and the Norse Vikings of Scandinavia. The Byzantine Empire has been described as a maritime empire by numerous historians (Miller), and the Norse Empire’s naval advancements were a major reason for its success (Hadingham). Both empires were known for their technological advancements in the field of ship

The angle of incline of the propeller showed to be the most influential factor when talking about the speed of the boat. To create an accurate measurement, removeable blocks of various angles where instilled onto the boat. Each test had different combinations that would be combined with an angle in an attempt to find the best angle. There were mixed results within the data making it difficult to decipher at the start.

The third method was a variant of the second. Barges built with horizontal planks linked by mortise-tenon joinery were constructed on or near shore and towed into position. Researchers believe that they had most likely been partially filled with concrete in shallow water to reduce their freeboard and susceptibility to the winds and waves and thus facilitate their transport to the desired location. When the barges had been towed to the desired location, they were topped off with concrete until they sank to the

CHAPTER: (1) Introduction 1.1 Problem Summary and Introduction: The goal for our group is to design a ping pong ball launcher. The launcher needs to be scheduled to launch one solo ping pong ball one at a time over a set obstacle and into a bucket of a chosen diameter. The determination is for the launcher to have the capability to launch five ping pong balls one at a time into the container within one minute, having none of the ping pong balls bounce out or miss the bucket. The launcher can be made out of any matter preferred and can launch the ping pong ball in any anticipated way, except by explosion.

If they are held to far apart they are going to do the splits; if the skies are not under control as they come out of the water they will crash making them unable to get up or stay up once the boat begins to pull them. Knowing to lean back just a bit with their knees bent in front of them, assists in controlling the skies so they can slowly stand once the boat begins it forward motion the water, Make certain; if they think they may fall, they know to let go of the rope. Boycott telling them if they are not leaning back just slightly and are instead leaning too far forward this will cause them to smash their faces in the water while being pulled under by the boat, or worse, getting hit in the head with the skies while being rendered unconscious. Being ever so certain they understand that if they are leaning too far forward, it will cause them to become off balance and fall but do not tell them they could lose teeth or drown if this happens. Everyone knows this is a possibility, yet it rarely happens because we tell them if they think they are going to fall to let go of the
