sheave

A worker places a rope into the sheave of a pulley system.

Definition

1. Noun:

   • A grooved wheel or pulley: "sheave" refers to a wheel with a groove around its circumference, used in machinery to guide a rope, cable, or belt. It is a component of a pulley system.

2. Verb:

   • To gather and bind into a sheaf: "sheave" means to collect and tie stalks of grain, such as wheat or barley, into a bundle (a sheaf). This is an older, agricultural usage.

Usage Examples

Advanced Usage

• "Sheave" in mechanical contexts: Often used in compound terms like "sheave block" (a block containing one or more sheaves) or "sheave diameter" (the size of the wheel).

  • The sheave block was rigged to lift heavy loads. (The pulley block with grooved wheels was set up.)

• "Sheave" as a verb in historical agriculture: This usage is largely obsolete in modern farming but appears in historical texts.
