A composite bar has two segments of equal length L each. Both segments are made of same material but cross sectional area of segment OB is twice that of OA. The bar is kept on a smooth table with the joint at the origin of the co - ordinate system attached to the table. Temperature of the composite bar is uniformly raised by A0. Magnitude of the x co-ordinate of the joint is- LaAe A, calculate n. (Given that coefficient of linear thermal expansion for the material is aC) A composite bar has two segments of equal length L each.
