A short column tube of length L = 400 mm is loaded by a compressive force P. The outside and inside diameters are 70 mm and 60 mm, respectively. A strain gage is placed on the outside surface of the bar to measure normal strains in the longitudinal direction. E= 200 GPa. (a) If the measured strain is 550 x 10 -6 what is the shortening of the bar? (b) Determine the load P that will cause this strain. (c) Determine the compressive stress of the bar to produce this strain.
