A circular nylon pipe supports a downward load P, = 10kN, which is uniformly distributed around a cap plate at the top of the lower pipe. A second load Pa = 20 kN is applied upward at the top. The inner and outer diameters of the upper and lower parts of the pipe are d, = 30 mm, d, = 60 mm, d, = 55 mm, and d, = 65 mm, respectively. The bottom pipe has length 400 mm and the upper pipe has length 300 mm. Calculate the axial normal stress in each pipe segment. Calculate the strain in each pipe segment if the clongation of the upper pipe is 3.29 mm and the elongation of the bottom part is 1.25 mm.

Question

A circular nylon pipe supports a downward

load P, = 10kN, which is uniformly distributed

around a cap plate at the top of the lower pipe. A second load Pa

= 20 kN is applied upward at the

top. The inner and outer diameters of the upper and

lower parts of the pipe are d, = 30 mm, d, = 60 mm,

d, = 55 mm, and d, = 65 mm, respectively. The bottom pipe has length 400 mm and the upper pipe has length 300 mm.

  1. Calculate the axial normal stress in each pipe segment.
  2. Calculate the strain in each pipe segment if the clongation of the upper pipe is 3.29 mm and the elongation of the bottom part is 1.25 mm.
