A milling machine weighing 300 kg is installed on four supports, the average area of each of which is 50 cm2. What is the pressure of the machine on the floor?

To find the value of the pressure of the milling machine on the floor, we will use the formula: P = F / S = m * g / (S1 * n).

Constants and variables: m is the mass of the milling machine (m = 300 kg); g – acceleration due to gravity (g ≈ 9.8 m / s2); S1 – the average area of one support (S1 = 50 cm2 = 50 * 10 ^ -4 m2); n – number of supports (n = 4 pcs).

Calculation: P = m * g / (S1 * n) = 300 * 9.8 / (50 * 10 ^ -4 * 4) = 147 * 10 ^ 3 Pa = 147 kPa.

Answer: The floor pressure of the milling machine is 147 kPa.
