Sensitizer
Definition
a chemical that can potentially induce and allergic reaction after multiple exposures

AND if you want to be super fancy...
A sensitizer is defined by OSHA as "a chemical that causes a substantial proportion of exposed people or animals to develop an allergic reaction in normal tissue after repeated exposure to the chemical."
The condition of being sensitized to a chemical is also called chemical hypersensitivity.

Definition
This is yelled when something has been dropped. Do NOT look up. Try carefully move away from the person above.
Term
"Runaway!"
Definition
In terms of rigging, this means that something has caused the fly system to fail. This is very dangerous. Get out of the theatre immediately. IMMEDIATELY.

Free Body Diagram (FBD):

The purpose of free body diagram is to simplify the situation you are looking at.
In a FBD, the object is isolated, or free, from all of its support members, and shows all of the applied and reactive forces acting on it.

This is an example using a FBD to show the forces acting on a see-saw beam.
Term
Summation of forces
Definition

An object is in equilibrium when the algebraic sum of all the forces acting upon it equal zero. 

 

Loading and unloading are the most stressful events to the rigging system Movement changes the direction of forces Movement increases and decreases the force at different moments

Term
Bridle Forces
Definition
Forces seek equilibrium
Bridle angle is often over looked
Moment of force is greatly affected by angle
Term
Types of Forces
Definition
Compression
Tension
Shear
Torsion
Term
