Caster refers to several different concepts across various fields, including automotive engineering, furniture, and fantasy fiction. This article will explore the different meanings and applications of the term "caster."

Automotive Engineering

In automotive engineering, caster refers to the angle of the steering axis in relation to the vertical axis of the wheels. This angle is crucial for the stability and handling of a vehicle. A positive caster angle helps the vehicle maintain a straight line and improves steering feel, while a negative caster angle can make the vehicle more difficult to control.

Caster Angle

The caster angle is measured in degrees and can be adjusted to optimize vehicle performance. It is one of the key parameters in wheel alignment, along with camber and toe. Proper caster adjustment can enhance vehicle dynamics and tire wear.

Furniture

In the context of furniture, a caster is a small, swiveling wheel attached to the bottom of a piece of furniture, allowing it to be easily moved. Casters are commonly found on items such as office chairs, tables, and hospital beds.

Types of Casters

There are several types of casters, including:

• Rigid Casters: These casters can only move forward and backward.
• Swivel Casters: These casters can rotate 360 degrees, providing greater maneuverability.
• Brake Casters: These casters have a locking mechanism to prevent movement.

Fantasy Fiction

In fantasy fiction, a caster often refers to a character who can cast spells or use magic. These characters are typically known as wizards, sorcerers, or mages. The term "caster" is commonly used in role-playing games and fantasy literature.

Types of Casters

• Arcane Casters: These characters use arcane magic, often requiring extensive study and knowledge.
• Divine Casters: These characters draw their power from a divine source, such as a deity.
• Hybrid Casters: These characters combine elements of both arcane and divine magic.
