15 kip*ft 12 in 10 in 6 ft

Hi please present the solution clearly (preferabely on paper) with all steps so it is easier to understand since I have asked this question multiple times and I still don't get it. Thank you!

A bi-metallic cantilevered strip (i.e. horizontally composite beam) is to operate a switch at its free end. The steel and bronze strips are each 100 mm long and 15 mm x 1 mm in cross-section. Calculate the common radius of curvature and deflection at the free end for a temperature rise of 50 C. Take E = 200 GPa, a = 10 × 10-6 /C for steel and E = 120 GPa a = 20 x 106 /C for bronze.

The cross-section is shown to the right of the beam. For the cast iron beam what is the maximum deflection in the beam? Note: Young’s modulus is 172 GPa.
