Thegear system emerges as one of the most utilized concept in theengineering field. In most of the things that engineers make, gearsare usually used. Take for instance, when it comes to making ofobjects that will involve motion such as cars, motorcycles, andbicycles, engineers usually utilize the knowledge of gears in orderto succeed in the complete production of the objects (Jelaska14). Therefore, gears are vital objects, when it comes it comes tothe engineering field this implies that it is exceedingly criticalfor engineering students to have more information concerning gears.
have been in existence since the introduction of the rotatingmachinery. Because of their properties of force-multiplying, earlyengineers utilized gears for elevating heavy load like buildingmaterials. Besides, utilized the mechanical advantage of gears forship anchor hoists and pre-tensioning of catapult. Early gears wereusually made from wood having cylindrical pegs and were usuallylubricated by utilizing animal fat grease. On the other hand, gearswere also utilized in water and wind wheel machinery for increasingor decreasing the provided speed of rotation for application to thepumps and other machines that were powered. In the 18thcentury, gears were utilized for powering the textile machinery. Theindustrial revolution saw an increase in the utilization of metalgearing. In the 19thcentury, the science of gear design developed rapidly. Currently, themost vital new gear developments entails in the area of materials.The modern metallurgy has vastly augmented the useful life ofautomotive and industrial gears, while consumer electronics has takenplastic gearing to fresh levels of quiet operation and lubricant-freereliability.
Theattribute of the gears of having the capacity to decrease or increasethe speed of rotation is exceedingly significant since this is whatmakes engineers fond of using their science in producing variousobjects. For instance, the plastic gears are usually utilized ineither increasing or decreasing the rotating speed of electronicmachines. Besides, in objects like motors vehicles, the gears havethe same role of either decreasing or increasing the speed ofrotation. This is why drivers usually use different gear ratios, whenthey are driving on a hilly or sloppy region. On the other hand, whenengineers use gears, they help in making work simpler by mitigatingthe force that is used. For instance, when elevating objects from theground to a higher surface, or when cycling up a mountain. In thiscase, a person is likely to use less force compared to force thathe/she could have used without the presence of gears. Therefore, theattribute of gears of mitigating the force used in doing certain jobsmakes gears be considered by engineers.
are usually utilized in transmitting rotational motion amid machineryshafts. The moment gears of varied sizes and types become combined,they tend to change the rotation rate, the direction of the rotationaxis, and transform rotary motion to linear motion (Jelaska32). There are different gear systems utilized, which includeexternal spur gears, internal spur gears, rack and pinion, wormgears, and helical gears. Engineers utilize the external spur gearsin transmitting rotary motion amid parallel shafts and shafts rotatein opposing directions. The internal spur gears are utilized intransmitting rotary motion amid parallel shafts however, shaftsrotate in a similar direction. The rack and pinion gears are used intransmitting rotary motion into linear motion. Besides, the helicalgear can be utilized in transmitting power amid parallel shafts, ortransmitting power amid non-parallel shafts. This depends whether thegears are parallel or crossed helical gears. On the other hand, theworm gears usually offer high angular velocity mitigation amidnonintersecting shafts that are at right angles. Besides, they havethe capacity to transmit high tooth loads (Jelaska48).
Throughlooking at the attributes and nature of the gears, gears remain asuseful objects to the engineering. Although the engineering field hasdifferent sub-categories, it seems like almost every sub-categorymakes use of the gears (Jelaska28). Takes, for instance, as a locomotive engineer, the knowledge ofgears is significant since the engineer has to understand the gearsthat should increase or increase the rotating speed. On the otherhand, an electrical engineer will also require an understanding ofthe knowledge of gears since most electronics utilize the gearsystems. Therefore, gears emerge as significant scientific objectsthat cannot be distanced from the engineers. Hence, engineers need tohave all the necessary knowledge of gears since they are critical intheir lives and profession.

The capacity to decrease or increasethe speed of rotation is exceedingly significant since this makesengineers fond of using their science in producing various objects.Besides, they have the capacity of transmitting rotary motion intolinear motion. In addition, they make to use less power for example,when cycling. Hence, gears are critical and useful objects toengineers.
