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... Show more
