Study Notes
Internal Forces
- Internal forces maintain the structural integrity by holding various parts of a structure together.
Newton's Third Law
- States that for every action, there is an equal and opposite reaction, applicable between two bodies in contact with identical magnitudes, aligned along the same line, but opposite in direction.
Trusses
- Structures designed to support loads, typically stationary and fully constrained.
- Composed entirely of straight members linked at joints at the ends of each member, functioning as two-force members.
Two-Force Members
- Structural elements subjected to two equal and opposite forces, acting along the line of the member.
Frames
- Structures designed for load support, usually stationary and fully constrained.
- Include at least one multi-force member which experiences more than two forces.
Multi-Force Member
- Represents a structural member influenced by three or more forces, generally not directed along the member itself.
Machines
- Structures intended to transmit and modify forces.
- Always incorporate at least one multi-force member and feature moving components.
Rigid Truss
- A truss characterized as "rigid," meaning it maintains its shape and does not collapse under load.
Simple Truss
- Created by the sequential addition of members to a fundamental triangular truss configuration.
Compound Trusses
- Comprise multiple simple trusses that are rigidly interconnected, enhancing structural capabilities.
