On the support of which area should a load of 1 ton be placed so that it exerts a pressure of 10 kPa on the ground.

Initial data: m (mass of the load placed on the support) = 1 t = 10 ^ 3 kg; P (pressure that the mass of the load should exert on the ground) = 10 kPa = 10 * 10 ^ 3 Pa.

Reference values: g (acceleration due to gravity) = 10 m / s2.

The surface area of the support can be expressed from the formula for calculating the pressure: P = Ft / S = m * g / S, whence S = m * g / P.

Let’s perform the calculation: S = 10 ^ 3 * 10 / (10 * 10 ^ 3) = 1 m2.

Answer: The load must be placed on a support with an area of 1 m2.
