Flashcards

Load

A force, deformation, or acceleration applied to structural elements.

Stress

The force across a small boundary per unit area of that boundary, the internal forces that neighbouring particle of a continuous material exert on each other.

Gravitational Force

The pull of a particle or rigid bodies towards the center of the earth with a force proportional to the mass of the object.

Moment of Forces

A measure of its tendency to cause the object to rotate about a specific point or axis, and is the product of the force and its distance from the point or axis.
