I got a material property data for a steel as follows.
1.0.2% of proof load 358kg
2.0.2% of proof stress 28.64(kg/sqmm)
My questions are
1)what is proof load
2)what is 0.2% of proof load. Why 0.2%? Why not 0.3%
3)How this proof load is arrived while testing the specimin in a universal tensile testing machine?
