Using the stress strain relations you developed in part: 1. derive the theoretical torque versus angle of twist relationship for the cast iron and for the steel. a. for every angle of twist recorded in the lab, determine which part of the shaft cross section is in the linear elastic range, which part is in perfectly plastic range (if any) and which part is in strain hardening (if any). b. given the shearing stress-strain models you developed, derive the equations for the torque for each of the parts identified above.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
