Stuck with a problem abt linear thermal expansion of solid

  1. Apr 12, 2010 #1
    I just read a problem 2day...it's on linear thermal expansion of soild...can anyone guide me through....it says..." A sqaure ABCD is made with two different metals...the coefficient of thermal expansion of the metal which made AB & CD is alpha (don't know how to type alpha) & the same of the metal which made BC & AD is beta (??)..Now if the temperature of the system is increased by t. then prove the angle between the diagonals will change by (alpha - beta).t/2 " ?????

    can u pls help....

    thanks
