1.	A metallic rod having area of cross section A, Young's modulus Y, coefficient of linar expansion alpha and length L tied with two strong pillars. If the rod is heated through a temperature t ^(@)C then how much force is produced in rod ?
Answer» Solution :`Y = (F//A)/( L //L ) = (FL )/(AL)` where `l = L prop Delta t` `THEREFORE Y = (FL)/(AL prop DELTAT ) = (F)/(A prop Delta t )`
