Question

Mechanical advantage can be thought of as the factor by which a machine multiplies the force applied to it. An example is a wheel and axle simple machine, such as a Response area, contains a pedal gear and a wheel gear connected by a chain. It is the ratio between these gears that creates the mechanical advantage. If the gears are the same size, then there is Response area mechanical advantage. Changing the gear ratio Response area mechanical advantage by turning the wheel gear more revolutions for every turn of the pedal gear. Climbing hills uses a low gear ratio, Response area, and going fast uses a high gear ratio, Response area. All of the changes multiply the Response area to the Response area.

Answer 1

Mechanical advantage can be thought of as the factor by which a machine multiplies the force applied to it. An example is a wheel and axle simple machine, such as a bicycle. The bicycle contains a pedal gear and a wheel gear connected by a chain. It is the ratio between these gears that creates the mechanical advantage. If the gears are the same size, then there is **no** mechanical advantage. Changing the gear ratio **increases** mechanical advantage by turning the wheel gear more revolutions for every turn of the pedal gear. Climbing hills uses a low gear ratio, **which provides greater torque**, and going fast uses a high gear ratio, **which allows for higher speeds**. All of the changes multiply the **input force** to the **output force**.
