Lecture Material science: Part 2 - Mechanical properties of materials presented elastic deformation – bending of beams, hooke’s law, strain, stress, elastic energy, bridges, increasing the yield strength, reduce grain size. | Part 2 Mechanical Properties of Materials Elastic deformation - bending of beams Why study elastic deformation - Essential to predict how materials deform under applied forces - In order to choose best material for required function Examples of beams - Hockey sticks - Oars - AFM lever Hooke s Law ụnstretohộd spring Hooke S Law F -H Spring amxftmf k It takes twice as much force to stretch a spring twice as .
