Philadelphia gear or Farrel gear are two brands of force multiplier gears. They consist of a driven pinion gear meshed with a larger bull gear driving a machine. The rotational force (torque) exerted on the pinion is multiplied by the difference in size of the bull gear it is driving, converting the input shaft speed into greater torque at the output shaft running at a slower speed.
Some examples of force fits include pressing in bearings into a housing, driving gears onto a shaft, and assembling pins into a hole. These applications require an interference fit to securely hold the components together.
clock.
Some examples of simple machines that can help multiply speed include gears, pulleys, and levers. These machines work by trading off force for speed, allowing input forces to produce greater output speeds.

Some examples of multiplying force include using a lever to exert more force over a longer distance, employing pulleys to lift heavy objects with less effort, and utilizing gears to increase the output speed or torque of a machine. These mechanisms allow for the amplification of force to accomplish tasks that would otherwise require more strength or energy.

In physics, the "Strong Force" is the force that holds the nucleus of the atom together. It is the strongest force in nature.
