    One company, McDonald, pushed hard in Washington to prevent the technically more-advanced L1011 from being accepted in the commercial airline industry, only to see its candidate, the DC-10, later prove to be a safety nightmare.

In the end, Douglas' effort helped prevent acceptance of the L1011 for large-scale orders, and the plane ended production far too soon due to lowered order rate.

    Covers the basic concepts of the finite element method and their application to the analysis of plane structures and two-dimensional continuum problems in heat transfer, irrotational fluid flow, and elasticity. This revised edition includes a reorganization of topics and an increase in the number of homework problems. The emphasis on numerical illustrations make topis clear without heavy use of sophisticated mathematics.
