material selection properties-what are the requirement for the most
suitable structural material?
Ans: the structural material that combine stiffness and elasticity are
considered the most suitable material.
material selection properties-elasticity?
Ans: The ability of a material to bounce back after being disturbed
- the ability of the body to deform under stress, bend, stretch and
compress when the external forces are applied and return to its original
shapes when the forces are removed.
material selection properties-elastic limit?
,2|Page
Ans: Maximum stress that a material will withstand without permanent
deformation.
material selection properties-Ductile material
Ans: A material which can be drawn out into a wire. This implies that
plastic strain occurs under enough stress.
- the material that undergo plastic deformation before breakage are
called ductile material.
material selection properties-plastic deformation
Ans: permanent deformation caused by strain when stress exceeds a
certain value
material selection properties-Brittle material
,3|Page
Ans: A material that undergoes little deformation under increasing force,
until it breaks suddenly. example glass
material selection properties-stiffness?
Ans: The resistance of an elastic body to deflection by an applied force.
the force that is applied to the material to bring it to the elastic limit.
material selection properties-what is dimension stability of the
material?
Ans: the property of the material to keep its dimension properties
especially when the direct affect of the moisture content or atmosphere
are applied to it. dimension ability is important when considering material
selection.
material selection properties-water and vapor resistance
, 4|Page
Ans: the resistance to water and vapour is an important factor in selection
of the material for construction.
material selection properties-thermal conductivity
Ans: The ability of an object to transfer heat
material selection properties-material selection and light, radiant
heat, transmission ?
Ans: the material property that reflect or absorb light are important factors
for deciding a material selection
the reflection or absorption of radiant heat should also be considered in
selecting the material.
material selection properties- what is density and hardness of a
material?
