1.	A block of mass Mis susended fom a wire of length L area of cross section A and Young.s modulus Y. Find the elastic potential energy stored in the wire.
Answer» Solution :`U=(1)/(2)` stress STRAIN. Volume `U=(1)/(2)` stress `("stress")/(Y)A.L` `U=(1)/(2)(Mg)/(A).(Mg)/(AY)A.L=, U=(1)/(2)(M^(2)G^(2)L)/(AY)`
