The strain energy stored in a specimen when strained within the elastic limit is known as 

If concrete grade is M , then what would be the modular ratio

In a rectangular R.C.C beam , the ratio of maximum shear stress to average shear stress is

The moment distribution method is formulated by

The bending moment is maximum on a section where shear force

An externally indeterminate structure is the one in which

The approximate allowable stress in bending compression in RCC is

Along the neutral axis of a simply supported beam 

Approximate permissible tensile strength of concrete M15 , is
