Statics of Rigid Bodies

Mechanics of Fluids

Divided into Incompressible Fluids (Hydraulics) and Compressible Fluids.

Mass

Property of matter reflecting gravitational attraction and resistance to velocity change.

Force

Action by one body on another, characterized by point of application, magnitude, and direction.

Rigid Body

Composed of numerous particles maintaining fixed distances despite load applications.

Concentrated Force

Effect of load acting at a single point.

Newton's Law of Gravitation

Two particles attract each other with equal and opposite forces. Formula: F = (G * m1 * m2) / r².

Collinear Force System

A system where forces have a common line of action.

Parallel Force System

Forces that are parallel but do not meet at a point.

Non-Coplanar Forces

Forces whose lines of action do not lie in the same plane.

Non-Concurrent Force System

Lines of action do not converge at a point.
