PROBLEM \# 3[20 pts] Two metal plates that measure 6cm10cm0.5cm thick are to be glued together with epoxy glue, resulting in a block 6cm10cm1.0cm thick. The epoxy must be heated to 200C from the initial temperature of 25C in order to set. It is desired to achieve this set in 1 minute. The blocks are placed in an oven with a convective heat transfer coefficient of 600W/m2K. What oven temperature should be used to achieve the set in the desired time? Consider two cases: (a) The plates are made of brass with thermal conductivity of 111W/(mK) and thermal diffusivity of 33.9106m2/s. (b) The plates are made of steel with thermal conductivity 15.1W/(mK) and thermal diffusivity of 3.91106m2/s
