Question

A box of mass 450 kg has dimensions of 5m×10m×15m. Calculate the maximum pressure it can exert on the ground?

Answer 1

Answer 2

Mass of the box = 450 kg

Dimensions =$\\ 5m\times10m\times15m$

The force applied by the box would be due to its weight.

Force = $\\ Mass\times acceleration$

Acceleration = 9.8 g/m²

Force = $\\ 450 \times9.8$

  =4410 N

$\\Area = length \times breadth\\ = 5m\times10m \\ = 50 m^{2}$

The Pressure applied is given by = $\frac{force}{area}$

$\\ Pressure = \frac{4410}{50}$

$\\ =88.2\frac{N}{m^{2} }$

Hence, the maximum pressure exerted on the ground =88.2 N/m²
