A compression force applied to a material in opposite directions that slide past each other across a perpendicular plane.
The amount of force applied per unit area.
The amount of stress that will cause a material to deform permanently.
The SI unit of measure for force (abbreviation: N).
A permanent change in a material due to stress.
The weight of the materials in the structure itself and all major architectural or product features.
The amount a material distorts due to the force applied.
A structural member which projects beyond its support and is supported at only one end.
The tendency of a force to cause a rotation about a point or axis which in turn produces bending stresses.
A force that is pulling against something.
A twisting force.
Any load that is changing and/or in motion.
The pulling stress a material can withstand without tearing.
The change in a material due to stress but the material can return to its original shape when the stress is removed.
A load that is at rest or motionless.
A body that supports a load and will resist external forces without changing its shape, except for the elasticity of the material used.
A force that occurs when one side of an object is being compressed while the other is under tension.
A bowed structure that transfers its weight evenly. The base, or abutments, prevents the structure from spreading out.
A horizontal structural component that is designed to resist compression, bending, shear and torsion forces.
The direct relationship between the force applied and the amount of deformation that results.
A main horizontal, primary structural member spanning between two main supports which carries other members or vertical loads.
Energy that occurs on a body causing physical action and/or movement.
A plate used to connect structural steel members or to reinforce members.
A structure comprising of one or more triangular pieces meant to support loads while reducing material usage.
A force where two opposing forces are pushing exactly towards each other.
The weight of all objects including people in or on a structure. This also includes natural forces created by wind, water, snow or seismic activity.
The curvature of a beam created so that it will become straight once a load is placed on it.
The strength at which a member tested would fail with 95% confidence.
The amount multiplied by the maximum load expected used to design structures stronger than actually required.
A measure of the elasticity of a material defined as stress divided by strain.
