A beam is supported at its ends and carries a point load of 10 kN at mid-span and a UDL of 18 kN/m over its full length. Calculate the position of the neutral axis, the moment of inertia about the xx-axis, and the moment of inertia about the yy-axis.

5.1.1 The position of a neutral axis from the bottom. Step 1: Determine the total height of the cross-section. The total height H is the sum of the vertical dimensions: H = 100 mm + 300 mm + 200 mm + 300 mm + 100 mm = 1000 mm Step 2: Calculate the position of the neutral axis from the bottom. The cross-section is symmetrical about the horizontal axis (x-x axis). Therefore, the neutral axis (centroidal x-axis) is located at half the total

5.1.1 The position of a neutral axis from the bottom.

Determine the total height of the cross-section.
The total height $H$ is the sum of the vertical dimensions:
$H = 100 \text{ mm} + 300 \text{ mm} + 200 \text{ mm} + 300 \text{ mm} + 100 \text{ mm} = 1000 \text{ mm}$
Calculate the position of the neutral axis from the bottom.
The cross-section is symmetrical about the horizontal axis (x-x axis). Therefore, the neutral axis (centroidal x-axis) is located at half the total
