Question

A rectangular table top has length 1.8 m and width 1.2 m.

A force of 600 N is applied to the whole table top.
Calculate the pressure in N/m2 to the nearest integer.

Answer 1

The equation of pressure is given by:

`p = (f)/(s)`

where p is the pressure.

f is the applied force.

s is the surface area to which the force is applied.

I will start off by calculating the surface area of the table top given by:

`s = l * w = 1.8 * 1.2 = 2.16`

s=2.16 m²

We know that f=400 N, that is given.

`p = \frac{400 \: n}{2.16 \: m {}^(2) }`

Plug this on your calculator (excluding the units lol)

`p = 185.185 \frac{n}{m {}^(2) }`

`p = 185 \frac{n}{m {}^(2) }`
