Worksheet time: 10mins
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
