Stress is the Ratio of any given load to that of
corresponding area of cross-section under loading.

Where as the Strength means, it is the maximum stress, that
any member can withstand before reaching its breaking stage
in case of brittle materials or yielding stage in case of
elastic / volatile members.

Answer / shaji

Actually stress is the internal resistance/area when an external load is applied on the material and it depends greatly on the properties of the material. It is different from load/area.

Answer / shaji

if stress is simply load/area, the stress value for all the materials for given area should be same!. But it is not the case, stress is different for different materials. Hence stress is the internal resistive force developed due to external load/area expressed as N/mm2.
