Answer 1

Good morning Sir/Madam,

A) Non mechanical material properties:

Accoustical properties: Material with accoustical properties exhibit Low flow resistivity property as observed in Wool( high absorption coefficients for room reverberation, can be used in duct linings).

Atomic and chemical properties:

Chemical properties include Corrosion resistance, pH and atomic properties like bonding, melting and boiling point etc, are some non mechanical material properties.

Electrical properties include Electrical conductivity, conductivity, dielectric strength, etc.

Thermal properties include Thermal Conductivity, thermal diffusivity,etc

Magnetic properties include Diamagnetism, Hysteresis, Magneto resistance, permeability, etc.

Optical properties include Absorbency, photo sensitivity, Color, luminosity, scattering, transmittance, etc.

B) Mechanical properties of elasticity plastic materials:

It includes:

Strength, Hardness, toughness, Malleability,

Ductility, Brittle, Creep, etc.

C) Mechanical properties of Elastic Materials:

It includes:

Strength, hardness, stiffness, Young's modulus, etc
