Problem 1.6-4 A circular aluminum tube of length L- 600 mm is loaded in compression by forces P (see figure). The outside and inside diameters are d;-75 mm and dm 63 mm, respectively. A strain gage is placed on the outside of the tube to measure normal strains in the longitudinal direction. Assume that E-73 GPa and Poisson's ration v 0.33. Strain gage (a) (a) If the compressive stress in the tube is 57 MPa, what is the load P? (b) If the measured strain is e-781 x 10, what is the shortening Sof the tube? What is the percent change in its cross-sectional area? What is the volume change of the tube? (c) If the tube has a constant outer diameter of d, -75 mm along is entire length L but now has increased inner diameter d, with a normal stress of 70 MPa over the middle third, while the rest of the tube remains at normal stress of 57 MPa, what is the diameter d,? (b)
