Problem 1.2-4 A circular aluminum tube of length L = 400 mm is loaded in compression by forces P (see figure). The outside and inside diameters are 60 mm and 50 mm, respectively. A strain gage is placed on the outside of the bar to measure normal strains in the longitudinal direction. Strain gage L= 400 mm (a) If the measured strain in e = 550 X 10¬°, what is the shortening 8 of the bar? (b) If the compressive stress in the bar is intended to be 40 MPa, what should be the load P?
