Explain the classification of longitudinal stress? |
|
Answer» Solution :Longitudinal stress can be classified into TWO TYPES, tensile stress and compressive stress. Tensile stress : Internal force on the two sides of `Delta A` may pull each other, i.e., it is stretched by equal and oppositeforces. Then , the longitudinal stress is called tensile stress. Compressive stress : When forces acting on the two sides of `Delta A` push each other, `DELTAA` is pushed by equal and opposite forces at the two ENDS. In this case, `DeltaA` is said to beunder COMPRESSION. then , the longitudinalstress is called compressive stress. |
