Question $10$

Numerical problem $5$: The bar is restrained at the wall and pulled by a force $F$ on the

opposite side. The bar is $0\mathrm{.}5$ m long and has circular cross$-$section. The fiemeter of the

cross$-$section decreases from $5$ mm to $4\mathrm{.}918$ mm $.$ Poisson's ratio is $03$ and elastic modilus

is $($:${10}^9(Pa)$
