Question $6$

Numerical problem $2\mathrm{.}2$: Similar to the previous question, the pipe shown in the figure has the same circular cross$-$section

along the entire length. External force is $149$ kN and it acts in x $-$direction on the xy $-$plane. Normal failure stress is $119$

MPa $.$ The factor of safety is $2.$

Write the final solution in the box for this question.

Task: Determine the diameter $(4$ decimal places$)$ of the circular cross$-$section, in meters, at which the normal stress will

be equal to the allowable normal stress.
