wheel and axle gears

At one end of the axle, a wheel of a greater diameter is fixed. The axle and the wheel both rotate about the same axis. Ropes have been wound around both the wheel and the axle..

Figure above shows a wheel and axle. At one end of the axle, a wheel of a greater diameter is fixed. The axle and the wheel both rotate about the same axis. Ropes have been wound around both the wheel and the axleh..

Gears - Gears are like a continuously rotating lever. By using different sizes of wheels, and different numbers of teeth, you can use gears as force multipliers or as distance multipliers. Figure above shows two cogs one with twice as many teeth as the other...

Gear systems are very efficient at transferring energy. Some gear boxes are 95% efficient i.e., they only waste 5% of the energy they transfe..

In all the above examples, a machine either multiplies or reduces the effect of the force that is applied. A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a steep hill, we soon realize that we gain speed by applying gr..

They between the gears. Therefore, axles connected by gears are always synchronized exactly with one another..

From times immemorial, man has used machines to help him in his work. Today, we are dependent on machine for almost every task. When we think of machines we always tend to think of big and complicated units with many moving parts like wheels and rollers and gears and shaft..

An interaction which causes an acceleration is called a force. Only when we push a ball does it begin to move. A ball lying on a horizontal floor doesn't start to move all by itself. For that matter, take a parked a car on a horizontal road. Only when we activate the engine and engage the ..
