Properties and Characteristics of Materials

Are used to determine a material's behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized fixtures on a universal testing machine.

• Compression tests

• Tensile

• Shear test

• Tortion testing

Ohm’s Law relate the current (I) or time rate of charge passage to the applied voltage (V).

• TRUE

• FALSE

The electrical properties of materials can be determined by performing carefully laboratory experiments such as tensile test, compression test, shear test, torsion test, impact test and hardness test.

• True

• False

Is the minimum required temperature for a solid material to change into liquid.

• Specific Gravity

• Density

• Melting point

• Malleability

Creep is the property of material which indicates the tendency of material to move slowly and deform permanently under the influence of external mechanical stress.

• True

• False

Refers to the rate at which a chemical substance tends to undergo a chemical reaction in time.

• Surface tension

• Reactivity

• Corrosion resistance

• pH

A material property that is indicative of the extent to which a material expands upon heating, and has units of reciprocal temperature.

• Thermal expansion

• Thermal conductivity

• Thermal stresses

• Heat capacity

Electrical conductivity indicative of the ease with which a material is capable of conducting an electric current.

• True

• False

Materials are those through which light is transmitted diffusely; that is, light is scattered within the interior to the degree that objects are not clearly distinguishable when viewed through a specimen of the material.

• Radiation Intensity

• Transparent

• Refraction

• Translucent

When light passes from one transparent medium to another having a different index of refraction, some of it is reflected at the interface

• True

• False
