A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The coefficients of linear expansion of the two metals are αc and αB. On heating, the temperature of the strip goes up by ΔT and the strip bends to form an arc of radius of curvature R. Then R is.
  • a)
    proportional to ΔT
  • b)
    inversely proportional to ΔT
  • c)
    proportional to |αB – αC|
  • d)
