• ## Equilibrium Of Coplanar Forces Essay

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the resultant and then balancing the resultant with an equal and opposite force called the equilibrant. When drawing the different forces we needed to find the angle it made. For the F_1, angle we used the formula α+β, and for the F_2 angle, we used 180-(β+γ). For the second part, in order to find the sum of the x and y components separately we use ∑▒fx= F_1x+F_2x+F_3x and ∑▒fy= F_1y+F_2y+F_3y, respectively. After finding the sum of the x and y components, we find the resultant by plugging the values into R= √((∑▒〖fx)〗^2+(∑▒fy^2)). Then to find the angle of the resultant we use tan⁡θ=(∑▒fy)/(∑▒fx)→θ=〖tan^(-1) (〗⁡〖(∑▒fy)/(∑▒〖fx)〗)).〗 Lastly, in order to know the equilibrant we know that E=-R. In order to find out the amount of error we made we use the percent error formula: % error=|(x-x_std)/x_std |x100%. Equipment: Circular table stand label in degrees; ring and pin for centering; four pulleys; four weight-hangers, each with a mass of 50 grams; four 100 gram masses; four 50 gram…

• ## Medevac Or Dust-Off Essay

Commanders could now place soldiers strategically around the battle field knowing that their members would be reached and placed into the next higher level of medical care anywhere on the battlefield. This was made possible by dividing each Medevac unit into platoons and embedding them on Forward Operating Bases (FOB), in order to further extend their range. We could now place a single Medevac within a single region and then further divide them up into individual team sites consisting of 3 UH60…

• ## American Airlines Case 9/11

Kirksville Regional Airport in Kirksville, Missouri. There were fifteen individuals on board the aircraft when it crashed into trees. After striking the ground the aircraft was destroyed and after the impact a fire on the ground broke out because of the plane crash. The conditions of that night were IMC. (NTSB) History of the Flight It was on the night of October 19, 2004 when flight 5966 crashed just before runway 36 at Kirksville Regional Airport. This flight was on the regular scheduled…

• ## Falling Velocity And The Dispersal Ability Of A Beetle Seed

(Alsomitra macrocarpa) seeds. They have light wings with a large surface area. Its aerodynamic design allows it to glide several hundred meters. Its aerodynamic shape inspired the design of airplane (Walker,2009). Based on this we hypothesized that large surface area will decrease the falling velocity and the seeds will disperse farther because of increased air resistance. Methods: On September 1, 2017, we made artificial seeds based on Javan Cucumber vine glider seeds. We used aluminum foil,…

• ## First Airplane Research Paper

Airplane; a powered flying vehicle with fixed wings and a weight greater than that of the air it displaces. Airplanes to many are just aircrafts able to get them from point A to point B. They are also known to fly through the air for military uses. We all know what they are, but do we ever take the time to think about how they ever came around and who was able to invent such a great invention? On December 17, 1903, Orville and Wilber Wright were the first people ever to fly a gasoline powered,…

• ## Wilbur And Orville Wrights First Flight

Ohio, had a dream to build something that could fly, but most thought it was nothing more than a crazy idea. With the belief that the sky is the limit when it comes to what can come from imagination, they built the first aircraft in history that went airborne. In 1903 they created a man made craft made of stick and fabric that achieved what was thought in those days impossible. Wilbur and Orville did most of their research in Dayton, Ohio, but tested their plane in Kitty Hawk, North Carolina.…

• ## Aircraft Propulsion Essay

Introduction To understand aircraft propulsion it is important to understand the term propulsion first. Propulsion is a means of producing force required for movement of object. The propulsion system has some source of mechanical power and some means of using this power to generate force such as wheels, propellers, legs, etc. Nobody can precisely tell the origin of mankind’s desire to fly as it is lost in the distant past. There are legends of people strapping birdlike wings and jumping of a…

• ## How Does Temperature Affect A Drag Force

and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the induced drag of the lifting wing. The surface roughness of the object also affects the amount of drag. The material with smooth and waxed surface will produce…

• ## Drop Time Experiment

indirectly by the mass, creating an exponential line of best fit. I think this will happen because even though mass does not affect acceleration of free fall, it affects the area of a weaker material used for a parachute. I predict that because of the fact that the parachute is made of plastic, as seen on the picture, the more weight that is being added onto it, the more will it close in on itself, decreasing the area, increasing air resistance and the drop time together with it. I also predict…

• ## Monarch Butterfly

can be placed using small beads which are harmless to the specie. Basking postures which have been studied (Vielmeter, 1954) will be used to determine which basking method Danaus plexippus utilize often and to figure out which basking posture is favored to keep the specie warm. Time where the butterfly spends basking in the sun, as well as wing position will be recorded to determine the heat transfer…
