A320 Landing Gear System

Correct: enhanced vehicle control because the arms stay close to the body and maintain a more stable vertical body position

Training wheels or stabilisers are wheels that are mounted to a bicycle used to help children learn how to ride and develop their sense of balance on the bicycle. Once installed these wheels prevent countersteering and they let children learn how to use the handlebars and how to turn.

In conclusion, the purpose of this lab was to decide if the sizes of the paper helicopters would have an effect on their descent times. One theory was that if the size of the paper rotocopter increases, then their descent time will also increase.To determine the results of this experiment certain procedural steps were followed. Firstly all five of the rotocopter were cut out, and folded on the dotted line, the paperclip was used to hold the flaps on the bottom of the

As its main function is to reduce the friction, and providing bearing support, its conceivable failure is detected by testing during maintenance. the probability of failure is either wearing off the rolling element, or misalignment of bearing which is a result of failure of bearing spacer. The system effect due to this is difficulty in cornering the vehicle, harsh

Researchers should develop custom instruments (suitable to their needs) to study the cycling transportation performance, since there are no dedicated instruments in this field of research. In this study, we developed an operational Instrumented Probe Bicycle (IPB) that is designed, built, and tested. The IPB is a completely mobile system capable of collecting a variety of empirical data. Several IPBs have been created around the world, which are different from each other based on the type of data needed. Accordingly, data collection from IPB divides into two basic categories, internal bicycle data and external bicycle data. The internal data represent the bicycle movement characteristics (e.g. speed, and acceleration), or direct influences

Overall the paper well explained the context of the e-bike system. The author truly delivered the paper with good ethos, pathos, and logos. Started by informing the reader who they are, they built up a credibility. Their pathos comes when they used so many techniques such as compare and contrast, narration, and process. The logos were being delivered on their scientific method where they use testable questions and empiricism technique. The simplicity makes the writing looks concise, but at the same time it is easier for the reader to understand the article. Moreover, they also do the deep research on each variables that they need in this writing, because based on the data, the researchers have been doing the survey throughout the years and

Bicycle Braking systems are a means of which we are able to halt the movement of a bicycle through the expulsion of kinetic energy. The Kinetic potential energy that is present in a moving bicycle is

Drag, when air passes around the bob-sled it creates drag. This drag slows the bob-sled down. To minimize the amount of drag the bob-sled undergoes,

There were many important people, aircraft, and developments, which greatly contributed to aviation development, which ultimately impacted the World. Out of many aviation developments, I will write about an aircraft I take pleasure in seeing and hearing, the C-130 Hercules. I consider this aircraft has made a significant impact in the aviation industry, most in the dependability of the airframe and its illustrious design. Today, this aircraft is used for many organizations such as Military Ops, firefighting, and search and rescue. The military is the primary user of this aircraft, for it uses it for many tactical operations. But what makes this aircraft so grand? The ability to land on short runways and the ability to fly slow with load,

The model is set to the angle of 4.1 degrees and the 30 readings from the multitube manometer, which are connected to points on the aerofoil surface, are measured and recorded. Along with these readings the two tubes connected to the tunnel reference pressure tappings are recorded. These steps are repeated but with an angle of attack of 6.1 degrees. It was found from the experiment that the stall angle was around 8.8 degrees. This was found by increasing the angle of attack until the

The device that displayed the best motion had three wheels. The reason that the device with three wheels displayed the best motion might have been due to the fact that it was the most secure out of the two. The device was much more even than the device with four wheels, holding the front tire in place and making sure it did not add more mass to one side than the other. The device with four wheels had multiple instances where the front tires would lean more to one side than the other. The average distance the three-wheeled device traveled was 888 cm while the four-wheeled device traveled 486 cm, a 402 cm difference between the averages.

In this case we need to overcome the friction force from the axles, and tires to be able to power the vehicle by mousetraps far enough. There is a coefficient of friction between the axle and the bearing where the axle sits in the bearings and does not spin together so that is where most of the friction is created. The front wheels currently are hard rubber, and the rear wheels are currently cutting disks which are a hard material and very skinny, creating a very little amount of friction. The total force of friction would need to be less than the force of the mousetraps on the axle throughout the traps angular travel. Methods that were used to reduce friction consists of using lubrication on the axles to make it easier to spin, use skinnier wheels to reduce friction from the ground, and making the vehicle lighter with a simpler design. (See APPENDIX 1 for detailed

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

-The protractor of the aerofoil connected to the lift and drag voltmeters was then used to vary the aerofoil’s angle of attack from 0° to 20°. Lift and Drag voltage values measured for each angle were recorded and calibration coefficients of 6.7 and 6.4 were used to obtain force Newton values for lift and drag. The lift and drag forces obtained for each angle were then plugged into equations (3) and (4) to obtain lift and drag coefficients. Equation (5) was used to calculate a theoretical value for the lift coefficient.
