### CONTENT

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.

### OBJECTIVE

? Students will be able to draw a two- and three-dimensional free-body diagram for a
given mechanical system.
? Students will be able to determine forces at identified points in the system for a two and three-dimensional mechanical system at equilibrium.
? Students will be able to determine the motion of a particle, systems of particle or a
rigid body when the forces and masses in a mechanical system are known.
? Students will assess various methods and problem solving principles relative to forcemass
acceleration relations, work and energy, and impulse and momentum in
mechanical systems.
? Students will be able to generate solutions by identifying appropriate methods and
applying relevant problem solving principles for engineering problems.
