what is the difference between strength & stress ?

Stress (may be in tension or compression or shear)is the pressure developed on application of loads ,on a structure. Stress is the force per unit area, it depends on area of structure, while Strength is the resistance to maximum stress at the time of failure, it does not depend on area 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 carry loads. 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. strength is the maximum stress the structure can withstand. read less
