Heal generation solids

In recent years, proprietary catalysts lor advancement have been incorporated in precatalyzed liquid resins. Thus only the addition of bisphenol A is needed to produce solid epoxy resins. Use of the catalysis is claimed to provide resins free from branching which can occur in conventional fusion processes. Additionally, use of the catalysts results in rapid chain-extension reactions because of the high amount of heal generated in the processing. 

S-S2 Consider steady two-dimensional heat transfer in two long solid bars whose cross sections are given in the figure. The measured temperatures at selected points on the outer surfaces are as shown. The thermal conductivity of the body is k = 20 W/m C, and there is no heal generation, Using the finite difference method with a mesh size of A.ic = Ay = 1.0 cm,...
