Question

Чему равно давление на рельсы четырехосного вагона массой 60 т,если площадь данного колёса 10 см.квадрате

Answer 1

M=60т=60000кг   s=10см.кв=0,001м.кв
P=mg/s=60000*10/0,001=6*10^10Па=60ГПа

Answer 2

Calculating Pressure on the Rails

To calculate the pressure on the rails exerted by a four-axle wagon with a mass of 60 tons and a wheel area of 10 square centimeters, we can use the formula:

Pressure = Force / Area

Where: - Force = Weight of the wagon - Area = Area of the wheel

Calculation

Given: - Mass of the wagon = 60 tons - Area of the wheel = 10 square centimeters

We need to convert the mass from tons to kilograms: 1 ton = 1000 kilograms

So, the mass of the wagon in kilograms = 60 tons * 1000 kilograms/ton

Now, we can calculate the force exerted by the wagon on the rails using the formula: Force = Mass * Acceleration due to gravity

The acceleration due to gravity is approximately 9.81 m/s^2.

Calculation Steps

1. Convert the mass from tons to kilograms: - Mass = 60 tons * 1000 kilograms/ton - Mass = 60000 kilograms

2. Calculate the force exerted by the wagon: - Force = Mass * Acceleration due to gravity - Force = 60000 kilograms * 9.81 m/s^2

3. Calculate the pressure on the rails: - Pressure = Force / Area - Pressure = (60000 * 9.81) / 10

Result

The pressure on the rails exerted by the four-axle wagon with a mass of 60 tons and a wheel area of 10 square centimeters is approximately 58830 pascals.
