1) 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. If the measured strain is e of the bar? If the compressive stress in the bar is intended to be 40 MPa, what (a) 550 10 6, what is the shortening d (b) should be the load P? Strain gage P P -L = 400 mm
