Answer 2

Given:

Tension at the soffit of the beam with given m/z value as 5.74.

To find:

Find the m values.

Step-by-step explanation:

$\frac{m}{z}=5.74,b=250mm,d=600mm$

$Z = (250*\frac{600} {6} ^{2} )$

=$15*10^{6} mm^{3}$

=$(5.74*15*10^{6} )$

=$86.1*10^{6} nmm$

$=86.1knm$

Answer:

The m values M=86.1Knm.
