Students have asked these similar questions
If material A is observed to have twice the modulus of rigidity but the same Poisson's ratio and yield shear stress than that of material B, then which of
the following comparisons is always true?
Select one:
Material A can resist higher normal stresses than material B can before permanent normal deformations occur.
O b
For the same load that brings the materials to plastic behavior, material A will experience larger permanent shear deformations than material B.
Material A can resist higher shear stresses than material B before permanent shear deformations occur.
O d. Material B is has a lower ultimate stress than material A.
Note: Kindly give me both right answers.
A) Did the ductile materials (annealed and aluminium) react differently to the two different testing methods (hardness test vs. tensile test)? What does this say about the behaviour of ductile materials in compression vs. tension?
B) Did the brittle material (quenched) react differently to the two different testing methods (hardness test vs. tensile test)? What does this say about the behaviour of brittle materials in compression vs. tension?
