Aerodynamics

lift in a cross wind (allowing more vertical airflow), making the roadway stable up to wind speeds of 150 miles per hour. At the time the Tacoma Bridge was built, little was known about aerodynamics and wind dynamics, which may have lead to the falling of the bridge. The Tacoma Bridge was known to have some aerodynamic instability after construction, but the architects failed to notice this during the bridge’s…

Wiper blades are devices used to remove rain, debris, snow, and ice from the windscreen. They are also known as windshield wipers or windscreen wipers. They are used by most driven machines including motor vehicles, watercraft, train locomotives and aircraft. They are usually a legal requirement for most of these crafts. A wiper usually consists of metal arm balanced at one end and a long rubber blade attached to the other end. The metal arm is mostly powered by electric motor. The rubber blade…

we get stiff. This results in a struggle to drive our sleds properly, leading to a higher chance of crashing. Frustrat-ingly, we’re unable to wear anything thicker underneath our suits because anything too thick will lead to us being far less aerodynamic, and, in consequence, making us slower. To solve this dilemma, I came up with a suit of my own. Preferably, this suit would be both thinner and warmer than the average luge suit. In order for this project to work, an ultra-thin insulator would…

The mousetrap is the power source. The wheels, which are CD’s will have no traction if not for the balloons being wrapped around them. With the wheels being CD’s they are thin and therefore more aerodynamic and will help the velocity and speed of the car. Then with the pens being hollowed out, it helps with the air and power from the mousetrap to flow through the pen which is attached to the wheels and helps the energy be sent to the wheels and thus…

Is velocity the reason why a curveball drops? Statistics show that the velocity of a ball does not cause the curveball to drop. There are other variables involved like air pressure, rotation of the ball, and aerodynamics. These are very important factors when a baseball is thrown. A Big part of velocity is the air pressure, this is because of a separate topic called the Magnus Effect - a force exerted on a rapidly spinning cylinder or sphere moving through air in a direction at an angle to the…

THE THEORY OF PURRPETUAL MOTION Question: if you buttered the back of a cat, which way down would it land? Law 1: The Laws of Butterology demand that the butter must hit the ground. Law 2: The equally strict Laws of Feline Aerodynamics demand that the cat cannot smash its furry back - it must land on its feet. If the combined constructed of cat + butter were to land, nature would have no way to resolve this paradox (or purradox). Therefore it cannot fall. When a cat is dropped, it always…

and view it on the spot with your smartphone or on the GoPro itself. The TomTom and GoPro are both spectacular products. Physically the shape of the TomTom is more aerodynamic and would be best if it was used on a helmet, on top of a car, etc. The GoPro Hero 4 Silver would be best if it was used on a chest mount or where being aerodynamic is not an issue. You cannot go wrong with either choice. The next time you are flying down a slope, on the track with your motorcycle, Falling out of the sky…

TERM PAPER TXL752 Case Study Motorcycle Racing Protective Clothing By Ravi Sharma 2011TT10951 INTRODUCTION: Compared to car drivers, motorcyclists are more likely to be killed or severely injured in crashes during racing or off road riding. You’ll lose 1mm of flesh for every 1mph you're going over 30mph when you hit road. Hence riders wear armour to protect against injury from falling off, hitting other riders and bikes, debris kicked up from the rear wheel of leading bikes, and from…

NASA Space Shuttle is the first reusable space shuttle in the world and used to deliver astronauts and cargos into space and return to the Earth. The success of the space shuttle getting through the catastrophic forces when travelling into space and back again in serviceable form was credited to the ingenious engineers. First, the rocket engineers faced the problem that without any protection, the engines would self-destruct under extreme temperatures when travelling huge distances. In fact, at…

To identify the preferred rotation direction, a blower performance analysis is needed. A blower is usually an enclosed multiblade rotor that compresses air to a higher discharge pressure. Blower is also known as fan, but, traditionally, blowers do not discharge air at low pressure as some fans do. Figure 1.6 – CENTRIFUGAL BLOWER Dryers use centrifugal blower, where air is radially discharged from the impeller, (or fan wheel), so turns 90° from its inlet to its outlet (Figure 1.6). Air…
