PART 1
STATICS, STRESS AND STRAIN,
AND FLEXURAL ANALYSIS

Principles of Statics;
Geometric Properties of Areas

If a body remains in equilibrium under a system of forces, the following conditions
obtain:
1. The algebraic sum of the components of the forces in any given direction is zero.
2. 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.
