A tapered barABof solid circular cross section and lengthL(Fig. 2-13a) is
supported at endBand subjected to a tensile loadPat the free endA. The diameters of the bar at endsAandBaredAanddB, respectively.
Determine the elongation of the bar due to the loadP, assuming that the
angle of taper is small.
