    The wheel and axle is another simple machine that is used to move heavy objects with less effort. It consists of a wheel attached to a shaft or axle, and can be used to transport goods.
    The wheel and axle is a simple machine that consists of a circular object (the wheel) attached to a cylindrical shaft (the axle). This machine allows for the efficient movement of objects by reducing friction and enhancing the motion transfer. It has been used for various purposes throughout history.
    • Mechanical Advantage: The wheel and axle provides a mechanical advantage by enabling the application of force at a larger distance from the axle, resulting in increased output force.
    • Friction Reduction: The wheel and axle reduces friction by allowing objects to roll rather than slide, making it easier to move heavy loads.
    • Rotational Motion: It enables rotational motion where the wheel rotates around the fixed axle, converting linear force into circular motion.
    • Increased Speed: By increasing the diameter of the wheel relative to the axle, the wheel and axle system can increase speed, as the linear distance covered by the wheel is greater than the rotational distance at the axle.
    • Versatility: The wheel and axle can be applied to various contexts, including transportation, machinery, and everyday objects.

    A gear is a simple machine that is used to transmit power between two shafts. It consists of teeth that mesh with another gear, and can be used to increase or decrease speed or torque.
    A gear is a mechanical device with teeth that is used to transmit rotational force or motion between two or more rotating shafts. It functions by meshing with other gears to alter speed, torque or direction of rotation. Gears are commonly used in a variety of applications such as machinery, vehicles, clocks, and many other mechanical systems.
    • Number of Teeth: Gears can have various numbers of teeth, which determines the gear ratio and affects the rotational speed and torque.
    • Diameter: The diameter of a gear influences its mechanical advantage and contact ratio with other gears.
    • Pitch Circle Diameter: The pitch circle diameter is the circle that defines the point of contact between two meshing gears.
    • Module: Module is a measure of gear size and refers to the ratio of the pitch circle diameter to the number of teeth.
    • Pressure Angle: The pressure angle is the angle between the line of action and a line perpendicular to the gear's axis.
