Problem $5\mathrm{.}11$

Problem Statement: A bar of high$-$strength aluminum allow is $150$ mm long and has a circular

cross section of diameter $40$ mm $.$ It is subjected to a tensile load of $250$ kN $,$ which gives a stress

well below the material's yield strength. Determine the following:

a$)$ stress in the length direction,

b$)$ strain in the length direction,

c$)$ strain in the transverse direction,

d$)$ length while under load, and

e$)$ diameter while under load.
