Theory and Practice of Minimum Weight Design

  • J.-M. Lagache
Conference paper


The present paper relates experiments that have taken place in Ecole Centrale de Paris, within the frame of annual projects, that are freely discussed between teachers and students. The project began about five years ago, with the initial,- and rather naive,- aim of illustrating Michell Theory [1,2,3,4] on simple mechanical examples. Preliminary discussions with students revealed that the design of a windmill was an appealing subject. Integration of a Michell torque transmission cantilever in a low speed vertical axis Savonius engine [5] was thought to be a gentle exercise, because of the low degree of mechanical sophistication of the machine.
