The steel pipe is filled with concrete and subjected to a compressive force of 80 kn. determine the average normal stress in the concrete and the steel due to this loading. the pipe has an outer diameter of 100 mm and an inner diameter of 50 mm. est = 200 gpa, ec = 30 gpa.

The stress on the steel is 3.88mPa and the stress on the concrete is 1.94mPa

Data;

We can solve for Pst and Pc

From equation(i) and (ii)

Let's solve for Pst

The normal stress between the concrete and steel can be calculated as

The stress on the steel is 3.88mPa and the stress on the concrete is 1.94mPa
