COMPOUND STRESS/COMPLEX STRESS SYSTEM

COMPOUND STRESS/COMPLEX STRESS SYSTEM

When normal and shear stresses act simultaneously  on an area (plane), it is called a complex or compound stress system. It will happen when the force is inclined to an area. The inclined force can be resolved into normal and tangential components.Normal component will cause normal stress and tangential component will cause the shear stress.

Practical Applications of Complex stresses:

(I) Beams

(ii) Shafts

(iii) Springs

(iv) Chimneys etc.
