In a compensated pendulum, two rods of different metals are used with their lengths in ratio of 2 : 3. The coefficients of linear expansions for metals in the ratio is

The value of coefficient of linear expansion (alpha) is ________ for metals than for alloys.

In a compensated pendulum a triangular frame ABC is made using two different metals. AB of length l_(1) is made using a metal having coefficient of linear expansion alpha_(1) . BC and AC of length l_(2) each have coefficient of linear expansion alpha_(2) . A heavy bob is attached at C. Pendulum can oscillate about the pivot D. Find (l_(2))/(l_(1)) so that distance of bob from the pivot point D does not change with change in temperature.
