"Statics is the branch of classical mechanics that is concerned with the analysis of force and torque acting on a physical system that does not experience an acceleration, but rather, is in static equilibrium with its environment."
The study of forces and moments in structures that are in equilibrium, or not moving.
Concepts of force and force systems: Understanding the basic concepts of force including scalar and vector quantities, resultant forces, free-body diagrams, and equilibrium.
Laws of motion: Familiarity with Newton's three laws of motion and how they apply to real-world structures.
Forces in structures: Comprehension of how forces act in various types of structures such as beams, trusses, and cables.
Moments and couples: Understanding the concept of moments and couples in relation to forces and how they affect structural stability.
Center of gravity and centroid: Knowledge about the center of gravity and centroid of a structure and how they can be used to calculate forces and moments.
Friction: Understanding the role of friction in structural design and how it can be calculated and reduced.
Static determinacy and indeterminacy: Understanding the difference between static determinacy and indeterminacy in structures and their impact on structural design.
Analysis of structures: Familiarity with different methods of analyzing structures including graphical, analytical, and numerical techniques.
Stress and strain: Understanding the concepts of stress and strain and how they affect structural design.
Shear force and bending moment diagrams: Knowledge about shear force and bending moment diagrams and how they are used to analyze and design structural elements such as beams.
Torsion: Understanding how torsion affects structural design and how it can be calculated and reduced.
Structural loads: Knowledge about different types of structural loads, including dead, live, wind, seismic, and snow loads, and their impact on structural design.
Structural materials: Understanding the properties of various structural materials such as steel, concrete, timber, and masonry, and their use in structural design.
Design codes and standards: Knowledge about design codes and standards, including American Institute of Steel Construction (AISC), American Concrete Institute (ACI), and International Building Code (IBC), and how to use them in structural design.
Structural safety and reliability: Understanding the importance of structural safety and reliability and how to ensure design integrity through proper analysis and testing.
Truss structures: These are structures that are made up of interconnected triangles.
Beam structures: These are structures that have a horizontal cross-section and are used to span spaces between supports.
Frame structures: These are structures made up of a network of interconnected beams and columns.
Shell structures: These structures have a curved surface that resists applied loads by tension and compression.
Cable structures: These are structures that use cables under tension to support a load.
Membrane structures: These are structures that support loads by tension in thin, flexible membranes.
Plate structures: These are structures that have a thin, flat surface and resist applied loads through flexure.
Arch structures: These are structures that have a curved shape and support loads through compression.
Suspension structures: These are structures that hang from cables or chains.
Tensegrity structures: These are structures that use tensioned cables to hold members in compression.
Retaining walls: These are structures that resist the lateral pressure of soil or water.
Domes: These are structures that have a curved shape and resist applied loads through compression.
Towers: These are structures that rise above ground level and support loads through a combination of tension and compression.
Bridges: These are structures that span a gap, such as a river or valley, and support the weight of the roadway or railway.
"Newton's second law states that F = ma (the bold font indicates a vector quantity, i.e. one with both magnitude and direction)."
"If a = 0, then F = 0."
"As for a system in static equilibrium, the acceleration equals zero, the system is either at rest, or its center of mass moves at constant velocity."
"M = Iα = 0."
"I is the moment of inertia of the mass."
"For a system where α = 0, it is also true that M = 0."
"Together, the equations F = ma = 0 (the 'first condition for equilibrium') and M = Iα = 0 (the 'second condition for equilibrium') can be used to solve for unknown quantities acting on the system."
