Question

explain sonority, malleability, ductility, brittleness, tensile strength.​

Answer 1

Answer:

Sonority- Sonority is loosely defined as the loudness of speech sounds relative to other sounds of the same pitch, length and stress, therefore sonority is often related to rankings for phones to their amplitude.

malleability- Malleability is a property of material by which in can be beaten to form its thin sheets.Most of the metals are malleable. Examples of malleable metals are zinc, iron, aluminum, copper,gold,silver, and lead. silver and gold are highly malleable.

Ductility- Ductility is a mechanical property commonly described as a material's amenability to drawing. In materials science, ductility is defined by the degree to which a material can sustain plastic deformation under tensile stress before failure.

Brittleness- A material is brittle if, when subjected to stress, it breaks with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a snapping sound. 

Tensile strength- Tensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material. ... When stresses less than the tensile strength are removed, a material returns either completely or partially to its original shape and size.

Answer 2

Sonority:-

A property in which a ringing sound is made when a metal strikes with any hard material, is known as sonority.

Example:-

• Metals are used for making bells.
• Metal wires are used in musical instruments too.

________________________________

The above examples showcase that all metals are sonorous.

________________________________

Malleability:-

The property by which metals can be hammered into thin sheets or foils is known as malleability.

Example:-

• Gold
• Silver
• Aluminium
• Copper

________________________________

Ductility:-

The property by which metals can be drawn into thin sheets is known as ductility.

Example:-

• Gold
• Silver
• Copper
• Aluminium
• Iron

________________________________

Brittleness:-

The property in which non metals break into pieces on hammering rather then converting into sheets or foils.

Example:-

• Sulphur
• Coal

________________________________

Tensile Strength:-

The property in which a substance is allowed to strain without breaking is said to be its tensile strength.

Example:-

• Iron
• Carbon fibre
