A metal bar of length 100mm is inserted between two rigid supports and its temperature is increased by $$10^o$$C. If the coefficient of thermal expansion is 12 x$$10^{-6}$$ per $$^o$$C and the Young’s modulus is 2 x $$10^{5}$$ MPa, the stress in the bar is

For an isotropic material, the relationship between the young’s modulus (E), shear modulus (G) and Poisson’s ratio (μ) is given by

The right triangular truss is made of members having equal cross sectional area of $$1550$$ $$m{m^2}$$ and Young's Modulus of $$2 \times {10^5}\,\,MPa.$$

The horizontal deflection of the joint $$Q$$ is

The influence line diagram $$(ILD)$$ shown is for the member
