Unformatted text preview: 10.115 A steel tube of 80-mm outer diameter is to carry a 93—kN load P with an eccentricity of 20 mm. The tubes available for use are made with wall thiclmesses in increments of 3 mm from 6 mm to 15 mm. Using the allowable-stress method, determine the lightest tube that can be used. Assume E= 200 GPa, are 250 MPa. SOLUTION PROBLEM 10.1 1 5 80—mm outer : diameter 3 37 726; 0.536: 27.24 6 3'4 IS‘lS 0.451 24.25 5! 31 2007 LZSS 2523!
