ENGR 2214 – Course Introduction
This course is at a level which gives students the background and mathematical tools to take subsequent specialty courses like Dynamics, Fluid Mechanics and Strength of Materials, etc.
For the student who wishes an overview of the subject, the topic coverage is broad enough to provide a comprehensive introduction.

What is statics?
Branch of physical sciences concerned with the state of rest or motion of bodies subjected to forces is called Mechanics.
The following diagram shows that Statics stands under solid mechanics of rigid bodies.

Statics is used to calculate forces in systems that don’t move, or move at constant velocity.
The application of physics to study motion is known as dynamics.
What is statics?Statics is actually the application of mathematics and basic
physics (Newton’s laws) to study forces in materials, machines and structures.
Forces are of interest to engineers for two reasons: – they cause materials to deform and break, and – they cause things to move.
Statics (ENGR 2214)Prof. S. Nasseri
What is Statics?Relation between forces and displacements
1. Determine the components of a force in rectangular or nonrectangular coordinates.
2. Determine the resultant of a system of forces. 3. Draw complete and correct free-body diagrams and write the
appropriate equilibrium equations from the free-body diagram. 4. Determine the support reactions on a structure.

What is Statics?Determine the internal reactions in a beam, draw correct shear-force and bending moment diagrams, and write equations for the shear-force and bending moment as functions of position along the beam.

What is Statics?
Trusses
Determine the connection forces in trusses and in general frame structures.
Statics (ENGR 2214)Prof. S. Nasseri
What is Statics?
Analyze systems that include frictional forces.

What is Statics?Locate the centroid of an area.(center of mass or center of gravity)
Calculate the mass moment of inertia, and the area moment of inertia.
