STATICS, STRESS AND STRAIN,
AND FLEXURAL ANALYSIS
Principles of Statics;
Geometric Properties of AreasIf a body remains in equilibrium under a system of forces, the following conditions
obtain:
- The algebraic sum of the components of the forces in any given direction is zero.
- The algebraic sum of the moments of the forces with respect to any given axis is zero.
The above statements are verbal expressions of the equations of equilibrium. In the ab-
sence of any notes to the contrary, a clockwise moment is considered positive; a counter-
clockwise moment, negative.
GRAPHICAL ANALYSIS OFA
FORCE SYSTEM
The body in Fig. \a is acted on by forces A, B, and C, as shown. Draw the vector repre-
senting the equilibrant of this system.
