Design Against Static Load topics include: Failure modes and stresses, cotter and knuckle joints, principal and thermal stresses, levers and fracture mechanics.

Design against static load should be based on permissible lateral and torsional deflections. Static loads are loads that do not change in magnitude or direction. 

Here are some considerations for design against static load:
The material is homogeneous.
The load is gradually applied.
The line of action of force P passes through the geometric axis of the cross-section.
The cross-section is uniform.
There is no stress concentration. 

Static loads can fail when they stop performing their intended function. This can happen when stress or deflection exceeds acceptable limits. Deformation is also considered a failure criterion. 

Static loads can be permanent, settlement, or accidental. 
Examples of static loads include:
People standing in a lift waiting for the doors to close.
The weight of a building bearing down on the ground.
A car parked on a road.
Filing cabinets or furniture that is placed on a floor.
A crane placed on top of a building. 

Static load testing is a type of load testing that measures a design's axial tension or compression. It can also measure a design's deflected shape under lateral load.
