margin of safety

Thân thiện

An engineer calculates the margin of safety for a new bridge design.

Definition

Noun: 1. The margin required in order to insure safety: The amount by which a system's actual or available capacity exceeds the minimum required for safe operation. It is a buffer or allowance for error, uncertainty, or unforeseen stress. * In engineering, the margin of safety is the strength of the material minus the anticipated stress.

Usage

The term "margin of safety" is used to describe a calculated or inherent buffer that prevents failure. It is a critical concept in fields like engineering, finance, and project management, where it quantifies the degree of safety or risk.

Examples
