Q1. [25%] a) A steel open-ended cylindrical tube is subjected to an internal pressure of Pi. Compute the stresses Or, Ot, 01, and Tmax at the inner and outer surfaces of the tube as well as at mid wall thickness r = 45 mm. Data are as follows: E = 200 GPa, d = 80 mm, do = 100 mm, P = 20 MPa b) If the internally pressurized tube in Part (a) is not one integral piece of material, but composed of two concentric tubes of the same material press-fitted to each other with a radial interference of 72 m, calculate the stresses r, and t at the inner and outer surfaces of both tubes. Data are as follows: E=200 GPa, di,inner = 80 mm, do,inner = 90 mm, = di,outer 90 mm, do,outer = 100 mm, P = 20 MPa Q1.
