  1. Thomas Edison State CollegeSchool of Applied Science and Technology EGM-211-OL: Statics Background and Basic Concepts 1

  2. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Background Mechanics is the branch of physical science that deals with the state of rest or motion of bodies under the action of forces. Mechanics is the foundation for most engineering sciences and it is indispensable prerequisite to most engineering or technical courses. Mechanics is divided into three branches: Statics, Dynamics, and Strength of Materials.

  3. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Divisions of Mechanics Statics concerns the equilibrium of bodies under the action of balanced forces. Dynamics deals with the motions of bodies under the action of unbalanced forces. Strength of Materials deals with the relationships among the external forces applied to the bodies, the resulting stresses (internal forces), and deformation. The determination of the proper sizes of structural members to satisfy strength and deformation requirements is also important topics of Strength of Materials.

  4. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics In the study of Statics and Dynamics, all bodies are assumed to be perfectly rigid. A rigid body is a solid in which the distance between any two points in the body remains unchanged. This is an idealization. In reality, deformations do occur in all bodies when they are subjected to forces. However, the deformations are usually very small and they can be neglected without appreciable errors.

  5. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Basic Concepts in the Study of Statics Force and force systems – A force is any effect that may change the state of rest or motion of a body. It represents the action of one body on another. Various types of forces and their characteristics will be introduced. If there is more than one force acting on a body, a group of forces constitutes a force system. Various types of force systems and their characteristics will be introduced.

  6. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Coplanar force systems – If the lines of action of all the forces in the force system lie in the same plane, the force system is called a coplanar force system. Two key issues will be discussed: the resultant of a coplanar force system and the equilibrium of a coplanar force system. The resultant is a single force that is equivalent to the given force system. A body is in equilibrium when the resultant of all the external forces acting on the body is zero. This means that the forces acting on the body are completely balanced.

  7. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Concurrent force systems – If the lines of action of all the forces in the force system pass through a common point, the force system is called a concurrent force system. Note that all the forces are not necessary in the same plane. Two key issues will be discussed: the resultant of a concurrent force system and the equilibrium of a concurrent force system.

  8. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Spatial force systems – If the lines of action of all the forces in the force system do not lie in the same plane, the force system is called a spatial force system. Note that spatial force system can be either concurrent or non-concurrent. Two key issues will be discussed: the resultant of a spatial force system and the equilibrium of a spatial force system.

  9. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Moment of a force – The ability of a force to rotate a body is called the moment of a force. The calculations of moment and its rotational effects will be introduced.

  10. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Geometric properties of a cross-section and a volume – The effect of a force is dependent not only on force itself but also on geometric shapes. Thus, geometric properties must be introduced.

  11. Thomas Edison State College, School of Applied Science and TechnologyBackground/Basic Concepts for EGM-211-OL: Statics Mathematics and unit systems – Study of Statics requires a level of mathematics that does not include calculus. However, a working knowledge of algebra, geometry, vector, and trigonometry is essential. Thus, a review of necessary mathematics is included in the textbook.
