Engineering Mechanics Fundamentals

  • Definition of Engineering Mechanics
    • Branch of physics addressing the state of rest or motion of bodies under forces.
  • Newton's Laws of Motion (January 1687)
    1. First Law: A body at rest stays at rest, and a body in motion stays in motion unless acted upon by a net external force.
    2. Second Law: The acceleration of an object is dependent upon the net force acting upon the object and the object's mass, mathematically represented as: F = ma where F is the force, m is the mass, and a is the acceleration.
    3. Third Law: For every action, there is an equal and opposite reaction.

Fundamental Quantities and SI Units

  • SI Unit System Overview:
    • Length: meter (m)
    • Time: second (s)
    • Mass: kilogram (kg)
  • Derived
