Question: A steel bar of solid circular cross section and length L 2.5m is subjected to an axial tensile force T = 24kN and a bending

A steel bar of solid circular cross section and length L 2.5m is subjected to an axial tensile force T = 24kN and a bending moment M = 3.5kNm (see figure).
(a) Based upon an allowable stress in tension of 110Mpa, determine the required diameter of the bar; disregard the weight of the bar itself.
(b) Repeat (a) including the weight of the bar.
