1.	A load (M) suspended from a wire produces an elongation (e ) in the wire then find the rise in temperature required to produce same elongation in the same wire.
Answer» Solution :`Y=(((F)/(A)))/(((Deltal)/(l)))""alpha=(Deltal)/(l(Deltal))` `Deltal=(Mgl)/(AY)…….(1)""Deltal=lalpha Delta t……….(2)` But from data `(Mgl)/(AY)=l alphaDeltat rArr DELTAT=(Mg)/(AY alpha)`
