The two-axle trailer with a load has a mass of 3000 kg. Calculate the pressure exerted by the trailer on the road if the contact area of each wheel with the road is 150 cm2.
Pressure of a two-axle trailer on the road:
P = F / S, where F is the force of pressure of the mass of the trailer with a load (F = m * g, where m is the mass of the trailer with a load (m = 3000 kg), g is the acceleration of gravity (g = 10 m / s²)) , S is the total area of contact of the wheels with the road (S = 4S1, where S1 is the area of contact of one wheel with the road (S1 = 150 cm2 = 0.015 m2)).
P = F / S = m * g / 4S1 = 3000 * 10 / (4 * 0.015) = 500000 Pa = 500 kPa.
Answer: The pressure produced by the trailer on the road is 500 kPa.
