Stress-Strain Curve

Materials with stronger metallic bonds exhibit high malleability.

Which metal has maximum malleability.

 The ability of a material to undergo plastic deformation without rupture, when a compressive force is applied, is known as 

Two wires of the same material and length but cross sectional area in the ratio $1:2$ are used to suspend the same loads. The extension in them will be in the ratio

Ultimate tensile strength of a metallic wire depends on its 

Dimensional formula of modulus of elasticity is

What do you understand by the yield strength of a material?

A typical stress-strain curve for a wire of a metal wire is shown below:

If the point D and E are very close, the material is:

The elastic behaviour of a body can be turned into plastic behaviour under the larger deforming force.

What do you understand by the plastic deformation of a body?

Permanent set refers to plastic strain in a material beyond _____ limit.

Define permanent set.

Permanent set in a material is produced by subjecting it to

Draw stress$‐$strain curve for a metal and explain permanent set.

Permanent set refers to:

Diamond is a very good example of

Define the strength of a material.

If diamonds are very hard then why are they so easily shattered when smashed with a sledgehammer?

Define toughness of a material.

Define hardness of a material.
