Composite bar with end load (two segments)
The composite bar BCD in the figure is composed of an inner aluminum cylindrical core of length 2L=2 m and radius R=1 cm and a sleeve of steel of length L=1 m and thickness R=1 cm surrounding the aluminum core in the CD section of the bar. The Young’s moduli are: E(Al) = 70 GPa, and E(steel)=210 GPa. The bar is fixed at B and a concentrated tensile load F is applied at the free end D. The resulting total elongation of bar BCD, is δ=1 cm. Determine the normal stress in the steel sleeve. (in MPa)

Helpless it is, 184 MPA
Do you have figured out Problem 1 and 2?
Anyone?
