Answer

the neutral axis (centroidal x-axis) is located at half the total

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 HH is the sum of the vertical dimensions: H=100mm+300mm+200mm+300mm+100mm=1000mmH = 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
