What is the inner radius of curvature of the composite strip

Reference no: EM13509731

A bimetallic strip is made out of two strips of metal bonded together. Each strip is 20.0 cm long and 1.00 mm thick. One strip has a coefficient of thermal expansion 4.00 × 10-6/K and the other has a coefficient of thermal expansion 3.00 × 10-6/K. At 20.0°C the strip is straight. What is the inner radius of curvature of the composite strip at 200°C?
