  title={Leonardo Da Vinci ' S Tensile Strength Tests : Implications for the Discovery of Engineering Mechanics},
  author={JAY R. LUNDa and JOSEPH P. BYRNEb},
  • Published 2000
In one of Leonardo Da Vinci's notebooks, an experiment is described where strengths in tension are measured for various lengths of wire. The notebook indicates that the results of these experiments were that longer wires were weaker than shorter wires. This result de®nes classical mechanics of materials. This con ̄ict has been explained as a note-taking failure by Leonardo. This short note develops an alternative explanation, based on the likely heterogeneity of the mechanical properties of the… CONTINUE READING
