Fundamental concepts and principles of mechanics leading to the understanding of structures at different length scales, ranging from buildings, bridges, dams to molecules and small particles. Equilibrium of particles and rigid bodies; centroids and centers of gravity; analysis of forces in buildings, machines, nanostructures and molecules; friction; mechanics of deformable bodies; stress,strain; behavior and strength of materials under tension, compression, bending and torsion. Case studies on the design of engineering and naturel structures. Also part of the "core course" pools for the MAT, ME,TE degree programs.
