All concepts →A solid cube of side 1 m is kept at a room temperature of 32 °C. The coefficient of linear thermal expansion of the cube material is $1\times10^{-5}/^{\circ}\text{C}$ and the bulk...
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 = 2...
A steel bar is held by two fixed supports as shown in the figure and is subjected to an increase of temperature ΔT=100 °C. If the coefficient of thermal expansion and Young's modul...
An initially stress-free massless elastic beam of length L and circular cross-section with diameter d (d <<< L) is held fixed between two walls as shown. The beam material has Youn...
A $$200$$ mm long, stress free rod at room temperature is held between two immovable rigid walls. The temperature of the rod is uniformly raised by $$250$$ o C. If the Young's modu...
