ENES221 Course Syllabus

Course Outcomes

Upon course completion, a student will be able to:

  • Compute the kinematic vectors of a particle using fixed, rotating, and moving coordinates.
  • Determine the forces required to create general motion of a particle.
  • Find the energy at any state and the change in energy between states for systems of particles.
  • Use the equations of motion to describe the rate of change of the linear momentum of a system of particles.
  • Compute the kinematic vectors of a rigid body using fixed, rotating, and moving coordinates in two dimensions.
  • Use calculus to find the moment of inertia of a rigid body.
  • Determine the forces and moments required to create general motion of a rigid body.
  • Find the energy at any state and the change in energy between states for systems of rigid parts.
  • Use the equations of motion to describe the rate of change of the angular momentum of a system of rigid parts and particles.
