Q. Consider a prismatic straight beam of length 𝐿 = 𝜋 m, pinned at the two ends as shown in the figure. The beam has a square cross-section of side p = 6 mm. The Young’s modulus E = 200 GPa, and the coefficient of thermal expansion 𝛼 = 3 × 10−6 K−1. The minimum temperature rise required to cause Euler buckling of the beam is K.
