3{)0 kips Problem I (35 points). A 6-ft length of a steel pipe of 12. inch outer diameter and 0.5-inch wall thickness is used as a short column to carry a 300-kip centric axial load. Knowing that E = 29 x 106 psi and that v = 0.30, determine a) the normal stress in the pipe b) the change in length of the pipe c) the change in its outer diameter d) the change in its wall thickness 4, - TG'- //) = /g.oo,,^tz g ft \^7t .\a, b) J, W-- (goo*Ye : A . 7t"*?xrc) CTto:1 YQ= -o3o -:-) .A --// br,*&-. : €,* n 12" = Gr ) + O,Oqt7t,8 b/R / ('/fr t6a = q e*,*"ou" s- €,t /6. 6 | kgi e7bPQ.rste) - o.o/ /2 (ze " /o3

a) b) c) Problem 2 (35 points). Two forces are applied to bracket BCD as shown. The steel used for both the control rcd AB and the pin at C has an ultimate normal sffess of 600 MPa and an ultimate shearing stress of 350 MPa. Determine the diameter of rod AB for which the factor of safety against failure will be 3.3. Determine
