A copper alloy pipe having yield stress ÏY = 290 MPa is to carry an axial tensile

A copper alloy pipe having yield stress σY = 290 MPa is to carry an axial tensile load P = 1500 kN [see figure part (a)]. A factor of safety of 1.8 against yielding is to be used.
(a) If the thickness t of the pipe is to be one-eighth of its outer diameter, what is the minimum required outer diameter dmin?
(b) Repeat part (a) if the tube has a hole of diameter d/10 drilled through the entire tube as shown in the figure [part (b)].
