PURPOSE The goal of this lab was to build a mousetrap powered car. The mousetrap car needed to travel fifteen feet. The purpose of building these mousetrap cars was to demonstrate our knowledge of motion, friction, force, distance, and energy. We have studied these concepts, and each one is a factor in the success of a mousetrap car.
Rubes machine was something that could incorporate the six simple machines lever, wedge, Pulley, wheel and axle, inclined plane, and screw. These all ended up in one way or another using Newton's three laws of motion. All having to do with an object will remain in motion until a force acts on it. An object will accelerate in the
As the arm rotates, the things in the thing experience centripetal acceleration which causes it to move out. The initial release position is such that the beam on the counterweight side makes an angle of 45° with the vertical. There is a lot of math required in finding the trajectory of the arms through. The trebuchet reached Europe during the early Middle Ages, or Dark Ages, in 500 AD and was used extensively by the French.
The Engineering of a Trebuchet To understand all the works and Physics behind a trebuchet, you must first understand all the individual parts of the trebuchet. Corresponding with most machines, the trebuchet is made up of different parts each having their own unique function. The five parts of the trebuchet are; the frame, the arm (or beam), the counterweight, the sling, and the guide chute (“How the Trebuchet Catapult Works”). Additionally, corresponding with most machines each part of the trebuchet can manipulated to create a different output.
The Space Race (1950-1960s), was an event that has influenced many generations of human race. In the Second half of the twentieth century, the world’s leading power, the United States of America and the Union of Socialist Republics (USSR) were engaged in a global competition, also known as the cold war, where they were trying to influence “non aligned” nations to take a side in the war. Military, political, scientific and diplomatic effort would affect the balance of power in the world, the loser will fall and will lost the ability to control his sphere of influence. Both nations went to the moon, however only the USA made it back to the Earth. The Space Race has revolutionized the world, people 's societal views , and helped humanity in several
28 Oct. 2015.) Luckily, now people have done great researches with advanced technology that answer some doubts we have of the world now and years
The main outreach of the United States government that explores new boundaries never touched before, invents products never thought possible before, and most importantly inspires people has had its budget slashed since its creation. In 1958, National Aeronautics and Space Administration was created in response to Sputnik, the first satellite launched by humans (Goldstein, 2007, p.1). Dwight D. Eisenhower did not want the United States to fall behind Russia in Aeronautics. This decision sparked what is known as the Space Race, within the Cold War between the Soviet Union and the US. Ever since then NASA has never been viewed in the same light as it was when the space race was going on. Currently, it has had to take a back seat to some other
It took centuries and nearly half of the continents to bring about such a weapon. Its towering frame and sling capable of launching missiles over 300 pounds was created by some of the most innovative people across the Eastern Hemisphere. Such a weapon was built for destruction, the trebuchet’s specialty being
According to Newton’s first law an object will travel in a straight line unless an outside force acts on it. In this experiment, the swinging stopper is swinging at steady speed but since it is being acted upon by an outside centripetal force and therefore it is accelerating. The swinging stopper was set up by placing the string with the stopper through a tube so that the stopper is hanging out the top side of the tube and the bottom side is the clip with the washers. In this experiment, three radii were selected and for each radius three trials were conducted. In each of the trials the swinger would swing the stopper in constant speed in a horizontal plane until 20 revolutions were completed.
Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.
Right from my childhood days, I was always eager to know how things work in surroundings. When I was given toys, I hardly played with them rather tried to dismantle it and try to know the mechanism running it. During school days, I have participated in many science exhibitions which further motivated me towards taking my knowledge and experience onto a higher and advanced level. With this desire and curiosity to understand machines and mechanisms, I chose to complete my graduation in Mechanical Engineering.
I have grown up watching “Discovery and National Geography channel” programs showing how Engineer’s solving inscrutable problems encountered during the construction of High rise buildings such as “Taipei World Financial Centre “or projects like “Rebuilding New York City 's Subway”. It made me mesmerized how we drive connections from nature to engineer these gravity deifying structures and how these modern structures are changing the face of earth. This sparked a wave of renewed curiosity and interest in understanding the engineering related to structure’s and I studied tenaciously to take Civil Engineering as under-graduate major.
