You will prepare and submit a term paper on Gear Ratio in Mechanisms. Your paper should be a minimum of 1250 words in length. Gears are also used to make work easier- a simple gear system can be devised to lift or move heavy weights (Gallagher, 2006). This is achieved through a proper combination of the gear ratio. Gear ratio refers to the ratio in the angular velocity of the input gear and the output gear, which is brought about by the difference in the number of teeth between the two gears. The aspect of variation in motions within a gear system is brought about by the difference in the number of teeth within the involved gears.

A combination of a gear kit and a motor can be used to make a lifting machine. This involves materials like motor, battery, circuit, six gears, and two sprockets. The six gears should be of varied teeth. The battery is used as the motive power to provide energy to run the motor. The connection between the motor and the battery is enhanced by a circuit, which is a combination of electrical wires.

The gears should be connected to each other through the sprockets, with the gears with many teeth directly connected to the motor. When the motor rotates by the impulse of electricity, the motion is impacted on the gear systems, whose motion is increased with the variation of the number of teeth in the gears (Gallagher, 2006). The increase in motion from the motor through the gearbox to the lifting lever leads to increased output which leads to a resultant force lifting an object. The complete machine should include a battery connected to a DC motor by electricity wires-probably made of copper, the motor connected to the gear system by use of the sprocket, and the gear system connected to the lifting system by the output sprocket.

The lifting of the weights is indirectly proportional to the number of gears used, and the sizes of their sprockets. The use of large gears will enhance little motion and lifting of little weight while the use of small gears brings about a greater force. A gear with a small one sprocket will provide a resultant force capable of lifting an approximated weight of 50grams.
