Reloaded Racing Car technologies

Weight: Weight of a car is a measure of how heavy or light it is. Weight is a force dependent on object’s mass. The mass of the object multiplied by the magnitude of gravitational field. This weight has a significant effect on the acceleration of the object.Lift: Lift is created by movement of the air around an object. It is the sum of all fluid dynamic forces on a body normal to the direction of external flow around the body.

Drag: Just as wind friction causes drag in an automobile, aerodynamic friction and displacement of air during creates aerodynamic DRAG. Drag occurs any time that air is displaced from its normal condition.Downforce: Downforce is simply the force acting down on the ground. On our car we have a force which acts down on the ground to keep the car fixed to the track as it is going around corners.Thrust: When a body is in motion a drag force is created which opposes the motion of the object so thrust can be the force produce in opposite direction to drag that is hig…

World in Gear Changing Technology

As we all know that Gears have existed since the development of rotating machinery. References to gears can be traced back to the 4th Century BC, where Aristotle wrote about wheels using friction between smooth surfaces to transmit motion.

The earliest known written reference to gears was circa 50 AD by Heron of Alexandria. He was a prolific inventor and mechanic who designed systems that utilized gears to lift heavy building objects. The early Greeks made use of metal gears with wedge-shaped teeth. Romans made use of gears in their mills.
Today, we enjoy the benefits of gears in everything from electric rotating toothbrushes to gigantic ships and jets. Gears are now made from a variety of substances, depending on the application and strength needed.

As we have sen in some applications, gears which  were also used as speed reducers. It then wasn’t until the Industrial Revolution some 1800 years later that increased the need for stronger gears and changed the way the world used power.
