The metallic hollow pipe shown in Figure Q1 is fixed at both its ends, and is under axial compression. The pipe has an external diameter D = 74 mm, an internal diameter d = 49 mm, and a length L = 5.06 m. The Young's Modulus of the metal used to manufacture the pipe is: E = 157.59 GPa. Figure Q1 Calculate the critical buckling load Pcrit using Euler's Formula. Assume the critical buckling load obtained through your calculations is valid in this case, and does not require verification. Use π = 3.14159 if needed. Express your answer in the unit: Newton (N). Report your answer to 2 decimal places.
A rod is subjected to a uni-axial load within linear elastic limit. When the change in the stress is 200 MPa, the change in the strain is 0.001. If the Poisson's ratio of the rod is 0.3, calculate the modulus of rigidity.

# 2-12. Normal Strain in rods constrained by walls with misfit Rods (1) and (2) were supposed to fit exactly between the rigid walls at A and C, as indicated in the figure below. However, rod (2) was manufactured a small amount, 8L, too long. A technician decides to lower the temperature of rod (2) by AT so that he can insert it in the space between B and C. When rod (2) returns to its initial temperature, the length of each rod is no longer the same as the original one, and the resulting strain is often called "residual strain"". Rod (1) has Young modulus E₁ = 74 GPa and cross-sectional area A = 1749 mm². Rod (2) has Young modulus E₂ = 204 GPa and same cross-sectional area A. Both rods have length L = 738 mm. L L (1) € = E₁,α₁, A B Ez az. A (2) Determine the resulting "residual" normal strain e in rod (1) when 8M = 9.10-¹ mm. -10-3 mm/mm
