A non-isotropic solid metal cube has coefficients of linear expansion as along the x-axis and
along the y-axis and z-axis. If the coefficient of volume expansion of the solid is
, then the value of C is:-
Two different wires having lengths L1 and L2 and respective temperature coefficients of linear expression are joined end to end. then the effective temperature coefficient of linear expansion is :
