The section in which the area of tensile steel is such that at the ultimate limit state, the ultimate compressive strain in concrete is reached, however the tensile strain in the reinforcing steel is less than the yield strain is known as?

The section in which the area of tensile steel is such that at the ultimate limit state, the ultimate compressive strain in concrete is reached, however the tensile strain in the reinforcing steel is less than the yield strain is known as? Correct Answer Over reinforced section

Over Reinforced Section:

When the stress in concrete reaches its permissible value before steel, then the section is failed with the sudden collapse of the structure. The resulting beam is known as an over-reinforced beam.

In over reinforced section the steels are not yielded fully, so over reinforced section is considered uneconomical.

Failure is also sudden in over reinforced section because concrete is brittle in nature and in over reinforced section concrete fails prior to steel.

The design of over reinforced section is also complicated.

Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, σ = yield strength and E = modulus of elasticity)

P, Q, R, Sand T are five crops that Babu grows. T is fast growing and more water demanding than R which gives more yield than T. P gives more yield than R and grows faster than Q. Q is more water demanding than T but is second lowest yielder, S is the slowest growing and least water demanding of all crops but gives highest yield. R is more water demanding and grows faster than P. Select the crop or crops that has/ have as many as crops that are more water demanding and as many as crops that give less yield than it.
