"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."
Study of the forces acting on and within structures in a state of equilibrium.
Forces: The fundamental concept of statics is the study of the forces that cause objects to be in equilibrium or motion.
Vectors: Understanding vectors is a must for understanding the direction and magnitude of forces in statics.
Newton's Laws of Motion: Newton's three laws of motion lay the foundation for understanding the principles of statics.
Equilibrium: The concept of equilibrium is critical to understanding statics. An object is in equilibrium when the net force and net torque acting on it are zero.
Free-body Diagrams: It's a diagram that shows all the forces acting on an object, how they are oriented and their point of application.
Mechanics of Rigid Bodies: Study of the motion of rigid bodies under the action of external forces.
Friction: The study of friction is important in understanding the forces that resist motion.
Center of Gravity: The center of gravity is the point in a body where the weight of the body can be considered to act.
Moment of Inertia: A measure of an object's resistance to rotation around a specific axis.
Torque: The measure of the rotational force applied to an object.
Stress and Strain: The study of the internal forces that act within a material.
Bending of Beams: The study of the deformation of a beam subject to external forces, including determination of the maximum stresses and deflection.
Torsion of Shafts: The study of the deformation of a shaft subject to twisting force.
Elasticity: The ability of a material to return to its original shape after being subjected to deformation.
Trusses: The analysis of trusses is important in designing structures that can withstand significant loads while minimizing weight.
Human body statics: It concerns the mechanical properties of the human body at rest, including bone and muscle tissue, and how it interacts with external forces.
Structural statics: This area focuses on the study of the equilibrium of structural objects at rest under applied external forces.
Material statics: This study focuses on the equilibrium of materials resting or suspended under external loads by considering their mechanical properties.
Fluid statics: This branch involves the analysis of the static behavior of fluids (liquids and gases) at rest under the action of gravity or a force field.
Soil statics: This area involves the study of the equilibrium of soil structures, including determining the stability of earth structures.
Bridge statics: This study deals with analyzing the stability of force and stress distributions in various types of bridges, as well as determine the strength and durability of bridge structure components.
Machine statics: This study deals with analyzing the static behavior of machines and determining the forces and torque required to keep them at rest.
Spacecraft statics: This branch of biomechanics deals with analyzing the stability and structural properties of spacecraft during launch and in outer space.
Aircraft statics: This area involves the analysis of the balance and stability of aircraft, including the behavior of certain components during flight.
Oceanic statics: This area studies the buoyancy, weight distribution, and stability of vessels under external forces such as water currents and wind.
Sports biomechanics: This study involves the application of static principles to develop and improve athletic performance and prevent injuries.
Manufacturing statics: This area concerns the static considerations in manufacturing, particularly in the design phase, to ensure product functionality and integrity.
Architectural statics: This study deals with the design and construction of buildings in such a way that they will withstand the external forces exerted on them.
Geomechanics: This area focuses on the stability of geological formations, including analyzing soil mechanics, rock mechanics, and engineering geology.
"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."
