Gear Ratios - Essay ExampleGears are used to suffer accommodate reduction in motorized machine parts and also make work easier.The article of belief of toss reduction is applied whereby a small pinion, the driving gear, spins very fast to provide luxuriant military unit to spin the wheel, the driven gear. The small pinion rotating fast will not provide comely torque. Torque is the force that tends to create motion. Torque is the product of force and distance covered. Motors designed produce wide torques are meant to operate at low speeds so as to increase their lifespan while producing the similar amount of power as a motor operating at higher speeds and producing smaller torque. government agency refers to the rate of doing work and its SI unit is the horsepower. This experiment studies how gear ratios can be used to take root torque.The apparatus used were RE 140 motor, six gears, small sprocket, big sprocket, weights, battery and the 917D kit for the gear reduction. The battery provided power to the RE 140 motor at the range of 1.5V and 3V.The experiment was conducted using a RE 140 motor and kit which included several combinations of gear reductions and masses of diametrical weights. The gear reduction combinations included small sprocket and big sprocket which were combined as shown in the forecast below.The circuit diagram featured a simple control circuit with the 3-volt motor connected to the power source and a toggle control switch for determining the direction of current. Current flow was to the left, mature and no current flow. The connections to the right and left set of terminals were insulated to ensure that the wires do not short circuit.The potency was supplied from a 3volt battery to the RE 140 motor which powered the 917 D gearbox. The gearbox provided six different gear ratios with the corresponding speed, revolutions per minute. The gears were tested with
