Find the pressure exerted by the mattress on the floor when the bed rests in its normal position. Assume that the entire lower surface of the bed makes contact with the floor. Give your answer in pascals.

Respuesta :

Since we assume that the entire lower surface of the bed makes contact with the floor it will exert 1.18*10^4 N of force.

Solution:

Find the volume of water filling the mattress:

V = (2.00 m)(2.00 m)(0.300 m)

   = 1.20 m^3

M = pV = (1000 kg/m^3) (1.20 m^3) = 1.20*10^3 kg

weight of the bed

Mg = (1.20*10^3) (9.8 m/s^2) = 1.18*10^4 N

What is pressure?

The force perpendicularly applied to an object's surface divided by the area over which it is dispersed is known as pressure. The pressure as compared to the surrounding air pressure is known as gauge pressure. To express pressure, a variety of units are employed.

What are the types of pressure?

  • Absolute pressure.
  • Gauge pressure.
  • Differential pressure.
  • Sealed pressure or vacuum pressure.
