Answer 1

Explanation:

For a Rectangular column cross section of size 200 mm x 300 mm, Moment of Inertia value to be used for finding out load carrying capacity of a column is

Answer 2

Given:

For a Rectangular column cross section of size 200 mm x 300 mm

To find:

Moment of Inertia value to be used for finding out load carrying capacity of a column is

Solution:

From given, we have,

A Rectangular column cross section of size 200 mm x 300 mm

The moment of inertia along the x-axis,

Ixx = bd³/12 = 0.2 × 0.3³ / 12 =  4.49 × 10^{-4} kg m²

The moment of inertia along the y-axis,

Iyy = b³d/12 = 0.2³ × 0.3 / 12 =  2 × 10^{-4} kg m²

The overall moment of inertia.

Ixy = 0
