Solution - draw the number thal mirrors the direction of the moments together follows: create the equation fer external radius Here, the outer radius the the pipeline is execute Substitute 1.90 in because that de 50.95 in woite the equalion because that inner radices ci di 1. Here the within radius of pipeline is di di = 1.6lin c; = 16 = 0.805 in
calculate the thickness of pipeline t=6-Ci t -0.95 -0.805 0.145 in.
