A reinforced concrete column consists of concrete filled with iron bars. Assume that iron occupies one-twentieth of the total cross-section area and Young's modulus of concrete is one-tenth of that of iron. The concrete column is under a compressive load `P`. Determine the fraction of load on the concrete.

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.

An iron bar of length L, cross-section area A and Young's modulus Y is pulled by a force F from both ends so as to produce an elongation l . Which of the following statements is correct?

The increase in energy of a metal bar of length L and cross-sectional area A when compressed with a load M along its length is (where, Y= Young's modulus of the material of metal bar)

The increase in energy of a metal bar of length L and cross-sectional area A when compressed with a load M along its length is (where, Y= Young's modulus of the material of metal bar)

A uniform bar of length 2 m and cross-sectional area 50cm^(2) is subjected to a tensile load 100 N. If Young's modulus of material of bar is 2xx10^(7)N//m^(2) and poisson's ratio is 0.4, then determine the volumetric strain.

A load of 1kg weight is attacheed to one end of a steel wire of cross sectional area 3mm^(2) and Young's modulus 10^(11) N//m^(2) . The other end is suspended vertically form a hook on a wall, then load is pulled horizonatally and relased. When the load passes through its lowest position the fractional change in length is (g = 10m//s^(2))

A load o f 1 kg weight is a attached to one end of a steel wire o f area of cross-section 3mm^(2) and Young's modulus 10^(11) N//m^(2) . The other end is suspended vertically from a hook on a wall , then the load is pulled horizontally and released .When the load passes through its lowest position the fraction al change in lenght is (Take g = 10m//s^(2))
