Mechanics Summary
-
Mechanics: A branch of physical science dealing with the effects of forces on objects.
- Rigid-Body Mechanics: Deals with the behavior of objects that do not deform under applied forces.
- Statics: Focuses on equilibrium, where forces balance, and bodies are either at rest or moving at a constant velocity.
- Dynamics: Deals with accelerated motion of bodies.
- Scalar: A quantity characterized by a single number (e.g., mass, temperature).
- Vector: A quantity with both magnitude and direction (e.g., velocity, force).
Coordinate Systems
- Two-dimensional coordinates system defined using x and y axes.
- Three-dimensional coordinates system defined using x, y, and z axes.
Units of Measurement
- US Customary units: Utilizes units like pounds (lb) for force, slugs for mass, feet for length, and seconds for time.
- SI units: Employs units like Newtons (N) for force, kilograms (kg) for mass, meters (m) for length, and seconds (s) for time.
Vector Representation
-
A vector is graphically represented using a line with an arrow (with magnitude and direction).
- Magnitude: Length of the line, denoted as |V|
- Direction: Angle (θ) from a reference line, describing the vector's orientation.
-
Cartesian Rectangular Components break down a vector into x and y (or x, y, and z components) for calculation ease. These components are usually along coordinate axes).
-
Vector component calculations using trigonometric functions such as cosine and sine.
