Definition

Noun: A gear mechanism is a system of gears designed to transmit and control motion, force, or speed for a specific mechanical function. It involves interlocking toothed wheels that change the direction, speed, or torque of a power source.

Examples

• Noun:
  • The bicycle's gear mechanism allows the rider to pedal efficiently on hills.
  • A fundamental part of a car's transmission is the complex gear mechanism that transfers power from the engine to the wheels.
  • Engineers are designing a more compact gear mechanism for the new robotic arm.

Advanced Usage

• "to engage a gear mechanism": to connect or activate the system of gears.
  • You must fully depress the clutch to smoothly engage the gear mechanism.
• "gear mechanism failure": a breakdown or malfunction within the gear system.
  • The vehicle was recalled due to a potential gear mechanism failure in the steering column.
