Topic hierarchy

8.1: Introduction
Torque is the force that causes objects to turn or rotate (i.e., the tendency of a force to rotate an object about an axis).
8.2: Conditions for Equilibrium
The first condition of equilibrium is that the net force in all directions must be zero.
8.3: Stability
An object in static equilibrium remains in the same state forever, but not all forms of equilibrium are the same.
8.4: Solving Statics Problems
When solving static problems, you need to identify all forces and torques, confirm directions, solve equations, and check the results.
8.5: Applications of Statics
A simple machine is a device that changes the direction of a force or augments a force; simple machines fall into six categories.
8.6: Elasticity, Stress, Strain, and Fracture
Elasticity is a measure of how much an object deforms (strain) when a given stress (force) is applied.
8.7: The Center of Gravity
The center of gravity is read mathematically as: ‘the position of the center of mass and weighted average of the position of the particles’.
8.8: Torque and Angular Acceleration
