The steel rods AB and BC are made of a steel for which = 300 MPa and E = 200 GPa. a) Write a computer program to calculate for values of a from 0 to 6 m, using 1-m increments, the maximum strain energy that can be acquired by the assembly without causing any permanent deformation. b) For each value of a considered, calculate the diameter of a uniform rod of length 6 m and of the same mass as the original assembly, and the maximum strain energy that could be acquired by this uniform rod without causing permanent deformation. 10-mm diameter B 6-mm diameter 6 m
