A Pipe (E = 110 GPa) Carries a Load $P_{\mathrm{I}}=120 \mathrm{kN}$

question 31

Multiple Choice

A pipe (E = 110 GPa) carries a load $P_{\mathrm{I}}=120 \mathrm{kN}$ at A and a uniformly distributed load $P_{2}=100 \mathrm{kN}$ on the cap plate at B. Initial pipe
Diameters and thicknesses are $d_{A B}=38 \mathrm{~mm}$ , $t_{A B}=12 \mathrm{~mm}$ , $d_{B C}=70 \mathrm{~mm}$ , and $t_{B C}=10 \mathrm{~mm}$ . Under loads $P_{1}$ and $P_{2}$ , wall thickness $t_{B C}$ increases by 0.0036 mm. Poisson's ratio ν for the pipe material is
Approximately:

• A) 0.27
• B) 0.30
• C) 0.31
• D) 0.34
