An aluminum tube is required to transmit an axial tensile force P = 33 k [see figure part (a)]. The thickness of the wall of the tube is to be 0.25 in.
(a) What is the minimum required outer diameter dmin if the allowable tensile stress is 12,000 psi?
(b) Repeat part (a) if the tube will have a hole of diameter d/10 at mid-length [see figure parts (b) and (c)].
