Question

Четырехколёсный прицеп с грузом имеет массу 2,5 т.Определите давление,оказываемое прицепом на дорогу,если площадь соприкосновения каждого колеса равна 125 см

Answer 1

p=F/S

где

F=mg

то есть2500

и тогда P = 2500 / 125 *10 в минус 4 *4 =500000 па

Answer 2

p=F/S  F=mg  F=2500 кг*10 Н/кг=25000 Н

S(всех колес)=0.0125 м^2 *4=0.05 м^2

p=25000 H/0.05 м^2=500 000 Па =500 кПа

Вот самый простой и удобный способ решения)

Calculation of Pressure Exerted by the Trailer on the Road

To determine the pressure exerted by the trailer on the road, we need to use the formula:

Pressure = Force / Area

In this case, the force is equal to the weight of the trailer, which is given as 2.5 tons. To convert this weight to kilograms, we multiply by 1000:

Weight = 2.5 tons * 1000 kg/ton = 2500 kg

The area of contact for each wheel is given as 125 cm². To convert this to square meters, we divide by 10,000:

Area = 125 cm² / 10,000 m²/cm² = 0.0125 m²

Now we can calculate the pressure:

Pressure = Weight / Area = 2500 kg / 0.0125 m² = 200,000 kg/m²

Therefore, the pressure exerted by the trailer on the road is 200,000 kg/m².
