According to Hooke’s law, within the elastic limit stress/strain = constant. This constant depends on the type of strain or the type of force acting. Tensile stress might result in compressional or elongative strain; however, a tangential stess can only cause a shearing strain. After crossing the elastic limit, the material undergoes elongation and beyond a stage beaks. All modulus of elastically are basically constants for the materials under stress.
Just on crossing the yield region, the material will have
- reduced stress
- increased stress
- breaking stress
- constant stress
Answer
(A) reduced stress
