The video shows how to carry out a finite element analysis of a beam structure using a Moto G smart phone. The computer programs must be DOS programs, & analysis is aided by "dosbox turbo" . The author has also successfully analysed a 124 element vibration of a rigid-jointed space frame; this was a 4 dimensional problem. The author believes that eventually, smart phones will be capable to handle large commercial computer packages. N.B. The Beam is simply-supported at Nodes 1 & 3, & NOT at Node 4!
