Briefly discuss the effect of σzz as to whether the effect is significant, secondary, or insignificant, providing an explanation.
A block of AISI 1020 steel with a yield strength of 260 MPa is subjected to a compressive stress σZZτxy
= -120 MPa and shear stress, .
A) What is the largest value of τXY that can be applied if the safety factor against yielding must be equal to 2?
B) Is there a large effect of σzz on the τxy required to cause yielding? Briefly discuss the effect of σzz as to whether the effect is significant, secondary, or insignificant, providing an explanation.
