Question

A rectangular table top has length 1.6 m and width 0.8 m. A force of 650 N is applied to the whole table top. Calculate the pressure in N/m2 to the nearest integer

Answer 1

Answer:

~508 $Nm^{-2}$ is the pressure.

Step-by-step explanation:

Given:

Length of rectangular table, $l = 1.6\ m$

Width of rectangular table, $w = 0.8\ m$

Force applied to whole table top, $F =650 N$

To find:

Pressure, $P = ?$

Formula for Pressure(in $Nm^{-2}$) is given as:

$P = \dfrac{F}{A}$

Where F is the force applied in N and

A is the area in $m^{2}$

Here A = Length $\times$ Width (Because table is rectangular in shape)

A = $l \times w$

A = 1.6 $\times$ 0.8 = 1.28 $m^{2}$

Now, finding Pressure:

$P = \dfrac{650}{1.28}\\\Rightarrow P = 507.8\ Nm^{-2}$

Pressure is $507.8\ Nm^{-2}$.

Nearest integer values is: ~508 $Nm^{-2}$
