The Iribarren number which is often denoted as Ir or ξ – is defined as: [5] = /, with =, where ξ is the Iribarren number, is the angle of the seaward slope of a structure, H is the wave height, L 0 is the deep-water wavelength, T is the period and g is the gravitational acceleration.

Engine braking is a viable method of controlling the speed at which a vehicle travels downhill. By shifting to a lower gear in a manual transmission, or applying "low" mode on an automatic transmission, engine braking reduces the need to repeatedly apply the foot brake, lowering the risk of the brakes overheating. [2]
Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...
Marks' Standard Handbook for Mechanical Engineers is a comprehensive handbook for the field of mechanical engineering. Originally based on the even older German Hütte, it was first published in 1916 by Lionel Simeon Marks. In 2017, its 12th edition, published by McGraw-Hill, marked the 100th anniversary of the work. The handbook was translated ...
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
No Jake brakes sign. The use of engine compression brakes may cause a vehicle to make a loud "growling", "machine gun", or "jackhammer" like exhaust noise, especially vehicles having no mufflers, which has led many communities in the United States, Canada, and Australia to prohibit compression braking within municipal limits.
It uses methods of analytical solid mechanics, structural engineering, safety engineering, probability theory, and catastrophe theory to calculate the load and stress in the structural components and analyze the safety of a damaged structure. There is a direct analogy between fracture mechanics of solid and structural fracture mechanics:
