A material being loaded in a) compression, b) tension, c)
shear.Uniaxial stress is expressed by
where F is the force [N] acting on an area A [m2].
But we cannot compare stress with strength.
the difference between the stress and strength is............
stress= load/ area ( n/mm2) .. it denotes that the load x will act in 1 mm2 of area of a structure,
strength denotes that max. stress upto which the structure get failure.
Strength is an extrinsic property of the material. It is
derived outcome of heat treatment processes. It is a
function of grain size, No of slip planes within a grain
etc. Therefore strength defines capacity of a material to
Stress is an internal resistance/force per unit area in the
material, generated due to application of external force.
Incidently, both have same units as strength is also
measured by force/area.
wat happens to the foundation when only live & dead loads
are considered( wind load is excluded) during the design of
a)only settlement in the internal structure and not external
b)only settlement in the external structure and not internal
c)no differential settlement
d)none of the above
