# The roller working on the laying of the highway puts on it a pressure of 400 kPa

The roller working on the laying of the highway puts on it a pressure of 400 kPa, the area of the roller support is 0.12 m2. what is the force of pressure.

As we know from the current school curriculum in physics, the pressure force can be calculated using the following formula F = p * S, where p is the pressure exerted and S is the surface area.

Let us determine with what force the roller exerts pressure, which works on the laying of a highway, when from the condition of the task it is known that the pressure corresponds to 400 kPa, while the area is equal to 0.12 m2:

400 kPa = 400000 Pa;

400,000 * 0.12 = 48,000.

Answer: With such initial data, the force will be equal to 48,000 N.
