Chapter 12: Q28. (page 479)

Find the weight to the nearest 10 kg, of the steel 1- beam shown below. Steel weighs 7860 kg/m³?

Short Answer

Expert verified

The weight of steel beam is $314400 \frac{kg}{m^{3}}$ .

Step by step solution

Step 1. Given information.

A figure provided in the question,

Step 2. Determine the weight.

Firstly, find the volume of steel beam,

$\begin{matrix} v = A (h) \\ = \frac{(30^{2} - 2 (12.5 \times 20))}{100} (10) [substituteandsimplify] \\ = 4 \times 10 [simplify] \\ = 40 m^{3} \end{matrix}$

Then, the weight of the steel is,

$\begin{matrix} w = 40 (7860) \\ = 314400 \frac{kg}{m^{3}} [multiply] \end{matrix}$
