A concrete column is reinforced with an iron rod in the middle. It is subjected to compression by a certain load. Assuming that the modulus of elasticity of concrete is one-tenth that of iron and the area of cross section of the iron is one-twentieth that of concrete, find the portion of the load acting on the concrete.

`(2/3)^(rd)` of load

`(1/3)^(rd)` of load

`(1/4)^(th)` of load

`(2/5)^(th)` of load

Text Solution

Verified by Experts

The correct Answer is:

Load on concrete `=(Y.20A)/(Y.20A + 10Y.A)=2/3`
