What kind of elastic materials are derived from a strain energy density function?

Civil Engineering : Strength of Materials - Quiz(MCQ)

Hypo elastic materials

Hyper elastic materials

Cauchy elastic materials

None of the above

Correct Answer : Hyper elastic materials

Explanation : The hyper elastic materials are derived from a strain energy density function. A model is hyper elastic if and only if it is possible to express the cauchy stress tensor as a function of the deformation gradient.

The structures constructed along are distributaries are called as _______

Inlets

Outlets

Channels

Distributaries

Correct Answer : Option (B) : Outlets

Explanation : An outlet is a simple and small irrigation structure which is constructed along the distributaries. The amount of water that is withdrawn through the outlet is in proportion to the area that is irrigated below respective point.
