A pipe of length / = 350 mm, external dimeter D = 80.0 mm and wall thickness t = 3.00 mm is connected to a square tube of length /2= 250, external side length s = 60.0 mm and wall thickness t2 = 8.00 mm. (Note: A pipe here refers to a circular cross section while a tube refers to a rectangular cross section). If the axial strains in the pipe and the tube are 0.00140 and 0.00250, respectively, calculate the final length of the whole assembly. Give your answer to 2 decimal places. rigid wall Pipe: dia = D 1 + 1 wall thick.= t 12 tube: side = s wall thick.= t F
