Gears and cogwheels are integral components of any rotating system that requires speed control, torque adjustment, or power direction change. These mechanical marvels utilize gear ratios to create a mechanical advantage. Today, gears and cogwheels are widely used in bicycles, gearboxes, and many other applications.


The wheel and axle are iconic mechanical innovations with immense influence. These simple machines are part of the ‘six simple machines’ group and have been essential in the modern world. The earliest evidence of the wheel and axle dates back to around 3360-3030 BC, and they continue to play a crucial role in the transportation and various mechanical systems.


Springs are elastic objects capable of storing mechanical energy. Typically made of steel, they come in coiled form and exert opposing forces when stretched or compressed. Springs have been used since the 15th century, initially in bows, and now they are found in almost every motor vehicle.


Electric motors convert electrical energy into mechanical motion. These motors utilize magnetic fields and winding currents to generate force. Ampere’s Force Law, discovered in 1820, forms the basis of electric motor functioning. The first practical electric motor was developed in 1828 by Hungarian physicist Anyos Jedlik, and today, electric motors are ubiquitous in various applications, from electric hand tools to cars.


Pulleys are wheels on an axle that change the direction of a cable or rope. They provide mechanical advantage and are commonly used to lift heavy objects. Pulleys were identified as one of the ‘six simple machines’ by Heron of Alexandria and are now integral components in systems such as engines, elevators, and water wells.


Steel, a vital material in mechanical engineering, has a rich history. Its production methods and quality have significantly evolved over time. In the 19th century, Henry Bessemer’s discovery of using oxygen to reduce carbon content revolutionized steel production, resulting in higher-quality and stronger steel.


Screws are cylindrical rods with spiraling helical ridges on the outside. They convert rotational motion into linear force and have been instrumental in numerous mechanical engineering applications. Screws are widely used in various industries, playing a critical role in fastening and assembling components.


Bearings reduce friction and allow objects to move smoothly in one constant motion or plane. They come in different shapes and sizes but serve the same purpose of reducing friction. Bearings are commonly found in bicycle wheels, car wheels, and numerous other rotating systems.


The reciprocating engine piston, invented by French physicist Denis Papin in 1690 AD, revolutionized the industrial revolution. This cylindrical object, contained within another cylinder and made airtight with sealing rings, transfers energy to the crankshaft in combustion engines.


Levers are simple machines consisting of a beam pivoting on a fulcrum. They provide mechanical advantage based on the location of the fulcrum. There are three types of levers: class 1, where the fulcrum is in the center; class 2, where the load is at the end; and class 3, where the effort is in the middle. Levers have made lifting objects easier and are found
