A copper and a tungsten plate having a thickness `sigma=2`mm eacha re riveted together so that at `0^@`C They form a flat bimetallic plate. Find the average radius of cuvature of this plate at `t=200^@C`. The coefficients of linear expansion for copper and tungsten are
`alpha_(cu)=1.7xx 10^-5//K` and `alpha_(W)=0.4xx10^(-5)//K`, respectively.
