A bimetallic strip of total thickness x is straight at temperature T. What is the radius of curvature of the strip, R, when it is heated to temperature T + DT? The coefficients of linear expansion of the two metals are a1 and a2, respectively, with a2 > a1. You may assume that each metal has thickness x/2, and you may assume that x << R.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. We will estimate this effect in this problem, assuming the thermal coefficient of volume expansion is 210 × 10-6/°C for sea water. 1. Calculate the change in length, in meters, of a column of water 1.00 km high for a temperature increase of 1.00°C. Note that this calculation is only approximate because ocean warming is not uniform with depth. ΔL(in m)=
