The word "antiskid brake" is spelled with the prefix "anti-" which means "against" or "opposed to," and the word "skid" which refers to a sudden and uncontrollable slide. The final syllable is pronounced as "brake," which refers to the mechanism used to slow or stop a moving vehicle. The IPA phonetic transcription for this word is /ˌæntiˈskɪd breɪk/, with stress on the second syllable of "skid" and the first syllable of "brake". This term is often used to describe safety features in modern cars and aircraft.
An antiskid brake, commonly known as an anti-lock braking system (ABS), is a technological device designed to prevent wheels from locking up during the braking process. It is typically used in vehicles such as cars, motorcycles, and airplanes to improve their braking performance and enhance overall safety on the road.
The primary function of an antiskid brake is to maintain traction on the road by modulating brake pressure on individual wheels to prevent them from skidding or sliding. This mechanism allows drivers to maintain steering control while braking, particularly in slippery or hazardous conditions.
The antiskid brake system works by utilizing sensors that monitor the rotational speed of each wheel. If a wheel starts to decelerate rapidly, indicating a potential lock-up, the system automatically reduces brake pressure at that specific wheel. This process is repeated multiple times per second to ensure continuous vehicle stability and prevent wheel lock-ups.
By preventing wheel lock-ups, antiskid brakes significantly reduce the stopping distance of a vehicle and help minimize the risk of accidents caused by uncontrollable slides or skids. This technology has become a standard automotive safety feature and is mandated in many countries.
In summary, an antiskid brake or anti-lock braking system is a sophisticated mechanism that prevents wheel lock-ups during braking, improving traction and control while helping to ensure safer driving conditions.
The word "antiskid brake" is a compound term that consists of two main parts: "anti-" and "skid brake".
The prefix "anti-" comes from the Greek word "antí", meaning "against" or "opposite". It is used to indicate opposition or the prevention of something. In this case, it signifies the purpose of the brake system, which is to prevent or counteract skidding.
The term "skid" refers to the sideways sliding or slipping of a vehicle's wheel or tires, resulting in a loss of traction with the road surface. Skidding can occur during intense braking or when driving on slippery surfaces.
Finally, the word "brake" refers to a device or mechanism used to slow down, stop, or control the movement of a vehicle by applying friction.
