What are the stages of fatigue failure? Stages of fatigue failure Stage 1- Initiation. Initiation is the most complex stage of fatigue fracture and is the stage most rigorously studied by researchers. Stage 2 – Propagation. The propagation stage of fatigue causes the microcrack to change direction and grow perpendicular to the tensile stress. Stage […]

What is degree of freedom in mechanics?
What is degree of freedom in mechanics? In physics, the degrees of freedom (DOF) of a mechanical system is the number of independent parameters that define its configuration or state. The exact constraint mechanical design method manages the degrees of freedom to neither underconstrain nor overconstrain a device. What is degree of freedom of a […]
What does revoked license mean?
What does revoked license mean? A revoked driver’s license means your license has been fully canceled and cannot be reinstated. It is possible to have your driver’s license revoked or even permanently revoked due to multiple driving offenses, medical conditions, and age. How do I get my revoked license back in California?

What type of insulation is used for ICFs?
What type of insulation is used for ICFs? Insulating concrete forms (ICFs) are a method of construction using components manufactured from expanded polystyrene (EPS). The forms are stacked, steel-reinforced, and then filled with concrete. When completed, ICF walls provide a solid monolithic structure. Where are insulated concrete forms used in the world? North America currently […]
Is work path dependent or independent?
Is work path dependent or independent? The work a conservative force does on an object is path-independent; the actual path taken by the object makes no difference. Why heat is a path dependent function? Two important examples of a path function are heat and work. These two functions are dependent on how the thermodynamic system […]
What is the function of a compressor in a vapor compression refrigeration system?
What is the function of a compressor in a vapor compression refrigeration system? It works as a pump to control the circulation of the refrigerant, and it adds pressure to the refrigerant, heating it up. The compressor also draws vapor away from the evaporator to maintain a lower pressure and lower temperature before sending it […]
Are all transmission fluids the same?
Are all transmission fluids the same? They are not all the same. Moreover, if your vehicle is still under warranty, using a fluid thatis not approved by the vehicle manufacturer will void the transmission warranty. Automobile companies develop automatic transmission fluids, or at least set specifications for them. But the car companies don’t make ATF. […]
When should you use a portable fire extinguisher?
When should you use a portable fire extinguisher? The first and most important purpose of a portable fire extinguisher is to help people escape. Portable fire extinguishers can clear fire away from your escape route or help keep an exit open for others. You should know where extinguishers are located and how to operate them. […]
Why are hardness tests performed?
Why are hardness tests performed? The application of hardness testing enables you to evaluate a material’s properties, such as strength, ductility and wear resistance, and so helps you determine whether a material or material treatment is suitable for the purpose you require. Why are different hardness tests and scales required? Different test scales were created […]
