An equilateral triangle ABC is formed by two Cu rods AB and BC and one Al rod. It is heated in such a way taht temperature of each rod increases by DeltaT . Find change in the angle ABC. [Coeff. of linear expansion for Cu is a_1 , Coeff. of linear expansion for Al is a_2l

An equilateral triangle ABC is formed by two copper rods AB and BC and one is aluminium rod which heated in such a way that temperature of each rod increases by DeltaT. Find change in the angle angleABC. (Coefficient of linear expansion for copper is alpha _(1). and for aluminium is alpha2 .).

When the temperature of a rod increases from t to t+Delta t , its moment of inertia increases from I to I+Delta I . If alpha is coefficient of linear expansion, the value of Delta I//I is

When the temperature of a rod increases from 1 to t. Delta t,the moment of inertia increases from 1 to 1+Delta.The coefficient of linear expansion of the rod is alpha.The ratio Delta I/I is :

The moment of inertia of a rod about its perpendicular bisector is I . When the temperature of the rod is increased by Delta T , the increase in the moment of inertia of the rod about the same axis is (Here , alpha is the coefficient of linear expansion of the rod )

The moment of inertia of a rod about its perpendicular bisector is I . When the temperature of the rod is increased by Delta T , the increase in the moment of inertia of the rod about the same axis is (Here , alpha is the coefficient of linear expansion of the rod )

The moment of ineratia of a uniform thin rod about its perpendicular bisector is I . If the temperature of the rod is increased by Deltat , the moment of inertia about perpendicular bisector increases by (coefficient of linear expansion of material of the rod is alpha ).
