Every forklift maintains its balance while carrying a load by using a cantilever system positioned on a fulcrum, which is the machine's front wheel axle. The cantilever system is similar to a simple teeter-totter, a device that also relies on a fulcrum to operate.Continue Reading
According to the Occupational Safety & Health Administration, a balanced forklift is highly stable and capable of carrying significant weight. The fulcrum, or pivot point, is the dividing line between the machine's weight and the load's weight.
Forklift America reports most forklifts indicate their load capacity on their respective data plates. The most important thing to remember when evaluating a load is that every object that is lifted has a center of gravity just as the forklift and load together have a center of gravity. This is why it is crucial for a forklift driver to keep the load within the triangular area between the front wheels, or fulcrum, and rear steering axle. It is this positioning of the load that keeps the loaded forklift stable. Placing the load too far away from the front axle is likely to cause the forklift to tip forward, while placing it too far to either side is likely to cause it to tip sideways.Learn more about Motion & Mechanics
The first class lever uses the fulcrum in between the applied force and load, the second class lever uses the load between the fulcrum and applied force and the third class lever uses the applied force between the fulcrum and the load. Levers help to lift heavy objects.Full Answer >
A toilet paper dispenser is an example of a wheel and axle. The rod that supports the roll of toilet paper serves as the axle, and the toilet paper roll serves as the wheel. Like all wheel and axle machines, the toilet paper rotates concentrically around the cylindrical holder, which is fastened in place.Full Answer >
To build a gyroscope, affix the handles of a bicycle to the axle of its wheel, knot a rope to a side and use it to hang the wheel mid-air. Alternatively, fold a piece of paper into strips with a thickness of 1/2 to 1 inch, and make it into a cylinder.Full Answer >
