"In this chapter we will review some of the important principles of statics and show how they are used tomdetermine the internal resultant loadings in a body. Afterwards the concepts of normal and shear stress will be introduced, an specific applications of the analysis and design of members subjected to an axial load or direct shear will be discussed."

COPLANAR
FORCES OR LINES THAT ARE ORIENTED SO THAT THEY BOTH MAY LIE IN THE SAME SINGLE (IMAGINARY) PLANE (FLAT SURFACE OF INFINITE EXTENSION).

FORCE
A PUSH OR A PULL

FORCE

LOAD
A FORCE WHICH REPRESENTS THE BURDEN THAT MUST BE SUPPORTED BY A STRUCTURE

MECHANICS
THE STUDY OF FORCE, ENERGY AND THE MOTION OF MASSES

MOMENT
A FORCE APPLIED TO AN OBJECT AT SOME DISTANCE FROM THE ROTATION AXIS THAT MAY CAUSE THE OBJECT TO ROTATE. THIS IS THE SAME AS A TORQUE. THE MOMENT IS CALCULATED AS THE PRODUCT OF A FORCE TIMES THE DIRSTANCE OF ITS POINT OF APPLICATION FROM THE AXIS OF ROTATION.

REACTION
A FORCE WHICH IS A RESPONSE OF A STRUCTURE OR ASSEMBLY TO AN APPLIED LOAD
