Web15 de mai. de 2024 · The arc-like bending happens because the two metals expand differently when heated. They have different thermal expansion coefficients $\alpha$. The bending allows the outer metal strip to expand more than the inner, so that they can expand differently while staying stuck together. Webb) The strips were rivetted together at 20 °C and formed a so-called bimetallic strip. Assume that it bends into an arc when heated. Determine which metal will be on the outer side of the arc and what will be the radius of the arc at 100 °C. Thickness of each strip is 1 mm. Notation Analysis Solution of a)
