roller coaster

Roller Coaster – an amusement ride developed for amusement parks. A specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more loops that briefly turn the rider upside down. Most roller coasters have multiple cars in which passengers sit and are restrained. The earliest amusement parks and roller coasters in the United States were built on Coney Island in New York during the late 1800s and early 1900s. More than 30 roller coasters were built on the island from 1884 through the 1930s. Built in 1927, the Cyclone Roller Coaster, … Continue reading roller coaster

paper airplanes

Paper planes are great projects. There are 1000s of designs, each with different flight characteristics. Some require cutting, others are made by folding only. Dihedral provides aerodynamic stability to your models by making them want to self-center during flight. Paper airplanes have no intelligent flight controls after they leave your hand, so the plane needs to be naturally stable or else it will crash. Designs perform better when some dihedral is added to the wings. Elevator is the aeronautical term for the hinged flap at the tail section of a plane that causes it to either climb (gain altitude) or … Continue reading paper airplanes

penny bridge

Penny Bridge – Make a bridge and see how many pennies it will support. Supplies 4 to 6 books (enough to make 2 stacks the same height) 5X8 index cards 10 -20 pennies for each team Scissors 1. Take an index card, gently bend the card so that it has a curve. Position the cardboard on a table so that it resembles an arch. Press down on the center of the arch. What happens to the ends of the cardboard? 2. Make 2 stacks of books with a gap of about 4 inches between them. Make sure the stacks are … Continue reading penny bridge

gasoline engine

Gasoline engine Gasoline engine and car Gasoline engine – internal combustion engine which is often used for automobiles, aircraft, small mobile vehicles such as lawnmowers or motorcycles, and outboard motors for boats. The most common engine of this type is a four-stroke cycle internal combustion engine that burns gasoline. Burning is initiated by an ignition system that fires a high voltage spark through a spark plug. Car Engines – Explained (video 6:00) – How engines work. What is an internal combustion engine? This video is the perfect introduction into learning about how cars work, starting with the most important part, … Continue reading gasoline engine

fluid mechanics

Fluid mechanics – the study of the physics of continuous materials which take the shape of their container. Fluids – In a mechanical view, a fluid is a substance that does not support tangential stress; that is why a fluid in rest has the shape of their containing vessel.And fluid in rest have zero shear stress Fluid statics Fluid dynamics Navier–Stokes equations Bernoulli’s principle Buoyancy Viscosity Newtonian Non-Newtonian Archimedes’ principle Pascal’s law Pressure Liquids Surface tension Capillary action Gases Atmosphere Boyle’s law Charles’s law Gay-Lussac’s law Combined gas law Plasma Rheology – the study of materials with both solid and … Continue reading fluid mechanics
