Question

Calculate Core of section for circular section of diameter 300mm​

Answer 1

Answer:

For a hollow circular column

Area of the column,

A=π4(D2−d2)=π4(3002−2202)=32672.56 mm2

Moment of inertai of the column section

I=π64(D4=d4)=π64(3004−2204)=282.62×106mm

Section Modulus (z) =Iy=282.62×106150=1.884×106mm3

Since the column is pinned at both ends

Left = L = 4m =4000mm

Answer 2

The core of section for circular section of diameter 300mm is 75mm.

Step-by-step explanation:

Given,

diameter = 300mm.

Find,

Core of section for circular section

Formula to be used for finding core of section for circular section of diameter 300mm is,

Diameter of core circular section = $\frac{Diameter}{4}$

Diameter of core circular section = $\frac{300}{4}$

Diameter of core circular section = 75mm.

Therefore, the core of section for circular section of diameter 300mm is 75mm.
