A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of 3.0×4.1cm in contact

tatiyna

Answer:

$5.22\cdot 10^5 Pa$

Step-by-step explanation:

The pressure exerted by an object is given by:

$p=\frac{F}{A}$

where

F is the magnitude of the force

A is the area of the surface perpendicular to the force

In this problem, the force is the weight of the books + the shelf, which is given by

$F=mg$

where

m = 262 kg is the total mass

$g=9.8 m/s^2$ is the acceleration of gravity

Substituting,

$F=(262)(9.8)=2568 N$

The area of the four legs is:

$A=4(3.0 cm\cdot 4.1 cm)=4(12.3 cm^2)=49.2 cm^2 = 49.2\cdot 10^{-4} m^2$

Therefore, the pressure exerted on them is:

$p=\frac{F}{A}=\frac{2568}{49.2\cdot 10^{-4}}=5.22\cdot 10^5 Pa$
