Full Scores Tire, From Full Scores Effort, AR565 Takes You To Bet On Questions!

Every year before the college entrance examination

Teachers will play the magic to bet questions

But the college entrance exam questions are not bets can be bets

Aulice also issued a special test paper

Come to try how many points can you get?

Good luck with the college entrance exam!

Literature Paper:

Read a scientific and technical article about tire materials and research to explain the impact and importance of raw materials on tires.

Answer:

1.As an important part of vehicles, the material of tires directly affects driving performance.

2.AR565 is made of high quality rubber material with excellent anti-cutting and explosion-proof performance.

The elastic steel wire structure improves stability and strength, making the tire able to withstand large loads and long-time high-frequency use to meet the needs on mining production.

Math Paper:

Suppose tire specification is 8.25R16LT, tread width of 228MM, and overall diameter of 860MM, what is the inner diameter of the tire?

1.

We can know from the tire specification 8.25R16LT:

8.25 indicates that tire section width is 8.25 inches so the tread width is 8.25 * 25.4 = 209.55 mm

R means this is a radial tire so the direction of tread cord is perpendicular to the rolling direction

16 means that the inner diameter of the tire is 16 inches, that is, 16 * 25.4 = 406.4 mm

LT represents the type of tire for light load radial tire

The tread width of 228mm is not equal to the 8.25 inches in the specification, because in the manufacturing process of tires, it is sometimes necessary to increase the tread width in order to increase the load capacity of the tire.

2.

Adopting high quality tire structure, AR565 can effectively withstand the pressure of large loads, thus increasing the tire's load-bearing capacity and service life.

The rigid shoulder structure can effectively prevent the tire from deformation and cracking after prolonged use, thus ensuring the stability and safety of the tire.

Physics Paper:

When driving, the area of a tire touching the ground and the tire tread has a great influence on the friction, find the coefficient of friction of the tire?

Answer:

1.

To solve the friction coefficient of a tire, it is necessary to know that for a tire, the coefficient of friction is influenced by the characteristics of tire and road surface.

The factors are: the material of tire and the ground, the state of the road and pressure between the tire, the pressure of the tire, speed and temperature of the window. In practice, the tire friction coefficient is a value with a wide range of variation and is generally adjusted according to the specific operating conditions.

2.

The stepped-down tread pattern prevents gravel embedding and increases friction between the tread and the road, providing more reliable durability, traction and operational stability, better adapted to the complex terrain and diverse surfaces of mines.

Optimized tire flat ratio: balance handling and comfort, effectively mitigate the vibration of the unevenness of the ground on the trucks during driving.

Keep steady all the time

Only then can you give a perfect answer
