The axially loaded bar ABCD shown in the figure is held between rigid supports. The bar has cross-sectional area A1 from A to C and 2A1 from C to D.
(a) Derive formulas for the reactions RA and RD at the ends of the bar.
(b) Determine the displacements δB and δC at points B and C, respectively.
(c) Draw an axial-displacement diagram (ADD) in which the abscissa is the distance from the left-hand support to any point in the bar and the ordinate is the horizontal displacement δ at that point.
