Answer:
This question is incomplete, here is the complete question:
A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of 350 MPa. Using the distortional-energy and maximum-shear-stress theories determine the factors of safety for the following plane stress states:
a) ax=100 MPa, ay=100 MPa
b) ax=100 MPa, ay= 50 MPa
c) ax=100 MPa, Txy=-75 MPa
d) ax=-50 MPa, ay=-75 MPa, Txy=-50 MPa
e) ax=100 MPa, a, 20 MPa, Txy=-20 MPa
Explanation:
due to how complex the solution is, The solved answer is in the attached images below.
