What is the speed for gears 1, 2, and 3?

The speed ranges for manual transmission gears 1 to 5 are as follows: 1. 1st gear: Typically around 10 km/h, suitable for normal starts or climbing steep slopes. 2. 2nd gear: Typically around 20 km/h, suitable for low-speed driving or climbing steep slopes. 3. 3rd gear: Typically between 20-40 km/h, commonly used for city driving. 4. 4th gear: Typically between 40-60 km/h. 5. 5th gear: Typically between 60-100 km/h, suitable for highway driving.

What does 'source' mean on a car steering wheel?

Steering wheel's 'source' refers to the audio mode switching function, allowing toggling between radio, CD, AUX, etc. Here are relevant details: 1. Multifunction Steering Wheel: A steering wheel equipped with function buttons on sides or below for easier driver operation. These controls may include audio system adjustments and air conditioning settings. 2. Car Audio System: Auto-audio refers to radio devices installed to alleviate travel monotony for drivers and passengers. Early vehicles used AM radios, later upgraded to AM/FM radios, cassette players, then CD players compatible with DCC and DAT digital audio. Modern car audio systems achieve high standards in sound quality, operation, and vibration resistance, maintaining stable performance and perfect sound even on rough roads.

Do symmetrical tread tires have a front and back side?

Symmetrical tread tires do have a front and back side. Here is the relevant information: 1. Tires: Tires are one of the most important components of a vehicle. Their main functions are to support the entire weight of the vehicle, bear the load of the car; transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to vehicle components, adapting to the high-speed performance of the vehicle and reducing noise during driving, ensuring driving safety, handling stability, comfort, and fuel economy. 2. Types of tires: Tires are broadly categorized into unidirectional tires, symmetrical tires, and asymmetrical tires. Unidirectional tires are mounted on the rim according to the rotation arrow on the tire sidewall, with the rotation arrow aligned with the forward direction of the vehicle. Asymmetrical tread tires require attention when installing them on the rim, ensuring that the side with the word 'outside' faces outward. For symmetrical tires, if the sidewall has white raised letters or a sidewall protection layer, the side with white raised letters or sidewall protection should be installed facing outward.

How many horsepower is 137kw?

137 kilowatts (kw) = 186 metric horsepower (PS). Here is additional information: 1. Metric horsepower: Also known as PS, its definition is entirely man-made and set very close to the value of imperial horsepower. One metric horsepower is defined as the ability to perform 75 kilogram-force meters of work per second. That is: 1 metric horsepower = 75 kilogram-force meters/second = 735 watts. 2. Imperial horsepower: The concept of the horsepower unit was named by James Watt, the improver of the steam engine, to indicate the power of his steam engine relative to the pulling power of horses. It is defined as 'the power of a horse capable of pulling 33,000 pounds at a speed of one foot per minute,' with watts (W) or kilowatts (kW) used as standard units.

What is the difference between 12a and 20a batteries?

Difference between 12a and 20a batteries: 1. Battery capacity: The 20Ah battery has 8Ah more capacity than the 12Ah battery; a 12Ah battery can discharge for 6 hours, while a 20Ah battery can discharge for 10 hours, providing 4 more hours of discharge. 2. Charger: A 20A charger for electric vehicles cannot charge a 12A battery because the 12Ah battery has a smaller capacity; normally, using a 12Ah charger for a 20Ah battery can extend the battery's lifespan. 3. Price: The 20Ah battery is more expensive; the 12Ah battery is relatively cheaper.

What is the torque for a 12mm connecting rod bolt?

There is no precise torque value as it depends on the bolt grade. The specification for a 12mm bolt corresponds to an M12 screw. The screw length refers to the effective length embedded in the object being fastened. For countersunk screws, the total length is considered; for half-countersunk screws, half the head length is added, while for cylindrical head screws, the length does not include the head dimension. For specifications, it's best to include the thread pitch in the full description. Additional information: The common method for bolt tightening is the medium torque control method. This method applies assembly torque to the bolt while it is in the elastic region, where torque and clamping force have a linear relationship, achieving the clamping effect on the parts. With the torque control method, the clamping stress of the bolt typically reaches 50% to 65% of the material's yield limit, meaning the bolt utilization rate is 50% to 65%, which is relatively low. The preload dispersion is ±16% to ±35%, which is relatively large.
