Question
In an engineering application, the material is a strip of iron with a fixed crystallographic structure subject
to a tensile load during operation. The part failed (yielded) during operation and needs to be replaced with
a component with better properties. You are told that two other iron strips had failed at yield stresses of
110 and 120 MPa, with grain sizes of 30 microns and 25 microns respectively. The current strip has a grain
size of 20 microns. The diameter of the rod is 1 mm and the load applied is 100 N. What is the yield stress of
the new part C and would you recommend it for operation?
Select one:
a. 140.5, no
Ob. 129.5, yes
OC.
120.5 MPa, no
O d. 133.5 MPa, yes
O e. 123.5 MPa, yes
