A circular aluminum tube of length L = 400 mm is loaded in compression by axial forces P at the ends. The ou inside diameters are 60 mm and 50 mm, respectively. A strain gage is placed on the outside of the bar to measur strains in the longitudinal direction (axial direction). (a) If the measured compressive strain is ɛ = 550×10-6 , what is the shortening ô of the bar? (b) If the compressive stress in the bar is intended to be 40 MPa, what should be the load P?
