Question

Какова площадь отпечатка одной шины автомобиля москвич если давление в его шинах составляет 98кПа. масса автомобиля 1,2 т. считая что вес автомобиля распределяется по всем колёсам равномерно

Answer 1

F=Sp
S=F/p=mg/p=1.2*10^3*9.8/9.8*10^4=0.12м

Answer 2

Calculation of the Tire Footprint Area

To calculate the footprint area of a car tire, we need to consider the tire pressure and the weight distribution of the vehicle. In this case, we have the following information:

- Tire pressure: 98 kPa - Vehicle weight: 1.2 tons (or 1200 kg) - Equal weight distribution on all four wheels

To calculate the tire footprint area, we can use the formula:

Footprint Area = Vehicle Weight / Tire Pressure

Let's plug in the values:

Footprint Area = 1200 kg / 98 kPa

To get the result in square meters, we need to convert the weight from kilograms to newtons (1 kg = 9.8 N) and the pressure from kilopascals to pascals (1 kPa = 1000 Pa):

Footprint Area = (1200 kg * 9.8 N/kg) / (98 kPa * 1000 Pa/kPa)

Simplifying the equation:

Footprint Area = 1200 N / 98000 Pa

Calculating the result:

Footprint Area = 0.0122 square meters

Therefore, the footprint area of one tire of the Moskvich car, considering the given tire pressure of 98 kPa and equal weight distribution, is approximately 0.0122 square meters.
