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 ?

Text Solution

Verified by Experts

`Y = (F//A)/( l //L ) = (FL )/(Al)` where `l = L prop Delta t`
`therefore Y = (FL)/(AL prop Deltat ) = (F)/(A prop Delta t )`

A wooden wheel of radius R is made of two semicircular part . The two parts are held together by a ring made of a metal strip of cross sectional area S and length L. L is slightly less than 2piR . To fit the ring on the wheel, it is heated so that its temperature rises by DeltaT and it just steps over the wheel. As it cools down to surrounding temperature, it process the semicircle parts together. If the coefficient of linear expansion of the metal is alpha , and it Young's modulus is Y, the force that one part of the wheel applies on the other part is :

One end of a long metallic wire of length (L) is tied to the ceiling. The other end is tied to a massless spring of spring constant . (K.A) mass (m) hangs freely from the free end of the spring.
