Les structures mécaniques qui nous entourent (automobile, avion, ponts…), se déforment sous l’effet de chargements extérieurs. Le rôle du concepteur est de faire en sorte que ces déformations ne nuisent pas au bon fonctionnement des structures.

As they tumble through space, objects like spacecraft move in dynamical ways. Understanding and predicting the equations that represent that motion is critical to the safety and efficacy of spacecraft mission development. Kinetics: Modeling the Motions of Spacecraft trains your skills in topics like rigid body angular momentum and kinetic energy expression shown in a coordinate frame agnostic manner, single and dual rigid body systems tumbling without the forces of external torque, how differential gravity across a rigid body is approximated to the first order to study disturbances in both the attitude and orbital motion, and how these systems change when general momentum exchange devices are introduced.

Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.

Archaeoastronomy is the “science of stars and stones”: it studies the relationships between the ancient monuments and the sky, in order to gain a better understanding of the ideas of the architects of the past and of their religious and symbolic world. The course provides the first complete, easy introduction to this fascinating discipline.

This course trains you in the skills needed to program specific orientation and achieve precise aiming goals for spacecraft moving through three dimensional space. First, we cover stability definitions of nonlinear dynamical systems, covering the difference between local and global stability. We then analyze and apply Lyapunov's Direct Method to prove these stability properties, and develop a nonlinear 3-axis attitude pointing control law using Lyapunov theory. Finally, we look at alternate feedback control laws and closed loop dynamics.

Learn about kinematics and dynamics in this calculus-based physics course. Mechanics is the study of the physics of motion and how it relates to applied forces. It lays the foundation of understanding the world around us through the how and why of motion.
