The greatest stress a material is capable of developing without deviation from straight line proportionality between strain and stress is called

• Elastic Limit

• Proportional Limit

• Ultimate Strength

• Rupture Strength

The greatest stress a material is capable of developing without a permanent elongation remaining upon a complete unloading of the specimen is

• Elastic Limit

• Proportional Limit

• Yield Point

• Ultimate Strength

The property of a material which makes its return to the original dimension when the load is removed is known as

• Plasticity

• Stiffness

• Elasticity

• Resillence

The ability of a material to deform in the plastic range without breakage or the ability to undergo considerable plastic deformation under tensile load before actual rupture is known as

• Plasticity

• Ductility

• Elasticity

• Brittleness

A property of a material where if the specimen be unloaded, it will not return to its original length, rather it will retain a permanent elongation sometimes called a permanent set.

• Plasticity

• Ductility

• Elasticity

• Stiffness

It is the slope of the straight line portion of the curve in stress-strain diagram.

• Poisson's ratio

• Modulus of rigidity

• Modulus of elasticity

• Yield strength

The stress at which there occurs a marked increase in strain without an increase in stress.

• Ultimate stress

• Yield stress

• Rupture strength

• Proportional limit

The maximum stress a material is capable of developing is known as

• Yield stress

• max stress

• rupture stress

The stress which acts in a direction perpendicular to the area is called
