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 Delta theta. Calculate the x co-ordinate of the joint if coefficient of linear thermal expansion for the material is alpha^(@)C^(-1)

1.	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 Delta theta. Calculate the x co-ordinate of the joint if coefficient of linear thermal expansion for the material is alpha^(@)C^(-1)
Answer» ANSWER :`-(Lalpha DELTA THETA)/6`
