A circular rod is loaded with a tension force that is progressively increased. Given this situation, the rod is likely to fail:
(a) On a plane at approximately 45 degrees to the line of action of the tensile force.
(b) On the plane at approximately 90 degrees to the line of action of the tensile force.
(c) It may fail according to (a) or (b) depending on the material properties.
(d) It will not fail unless another load, for example bending or torsion, is applied
