Question

Расчитайте давление которое производит вагон весом 200кН на рельсы если плошадь соприкосновения колес вагона с рельсами равна0,002м в квадрате

Answer 1

P(вес)=200кН=200000Н так как сила равна весу тела то формула давления будет иметь вид P=F/S= 200000Н/0.002м^2=100000000Па=1×10^8Па

Answer 2

Calculation of Pressure Exerted by a Wagon on Rails

To calculate the pressure exerted by a wagon on rails, we need to use the formula:

Pressure = Force / Area

Given: - Force (F) = 200 kN (kilonewtons) - Area (A) = 0.002 m^2 (square meters)

Let's substitute these values into the formula to calculate the pressure:

Pressure = 200 kN / 0.002 m^2

Calculating the pressure:

Pressure = 200,000 N / 0.002 m^2

Converting kilonewtons to newtons:

Pressure = 200,000,000 N / 0.002 m^2

Simplifying the calculation:

Pressure = 100,000,000,000 N/m^2

Therefore, the pressure exerted by the wagon on the rails is 100,000,000,000 N/m^2.
