A spring material made of high-grade steel, hard drawn (80% reduction), used for impact loads and moderately high temperatures.

A spring wire that is exceptionally good for withstanding impact loads and moderately high temperatures.

A type of coil spring where the helical coil is wrapped into a circle, forming an annular ring.

A type of spring where a thin, flat strip is wound into a plane spiral, usually anchored at the inside end.

The ratio of the length of a column to the radius of gyration of its cross-sectional area around the centroidal axis.

A screw that needs positive torque to be loosened, meaning it resists being loosened without force.

A type of key, also known as a tangential key

A device used to precisely measure speed.

The capacity of a material to absorb energy when it is deformed elastically and then, upon unloading, to release that energy. It represents how much energy a material can store and release without permanent deformation.

The strain energy per unit volume required to stress a material from an unloaded state to the point of yielding. It measures the amount of energy a material can store before permanent deformation occurs.

The ability of a material to absorb energy up to fracture. It represents the total energy a material can absorb before breaking.

A failure prediction theory that states a part will fail when the maximum shear stress exceeds a critical value. It applies to any combination of stresses.

A theory used in cyclic and impact loading that states damage at any stress level is proportional to the number of cycles. It helps predict fatigue failure.

A type of lubrication where the load-carrying surfaces of the bearing are separated by a relatively thick film of lubricant. The film is stable due to the flow of lubricant, preventing metal-to-metal contact.

The speed at which a rotating shaft becomes dynamically unstable. It's the speed at which the shaft starts to vibrate violently.

Another name for the Maximum-Shear-Stress Theory. It predicts failure based on the maximum shear stress.

States that equal volumes of ideal gases at the same temperature and pressure contain the same number of molecules, regardless of their chemical nature.

In a closed system, the total momentum remains constant, meaning the total momentum before a collision equals the total momentum after the collision.

In a closed system, the total energy remains constant, meaning energy cannot be created or destroyed, only transformed from one form to another.

States that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases.

The branch of mechanics that deals with the motion of objects without considering the forces that cause the motion.

A screw fastener with a head and a threaded shank, typically requiring a nut to hold it tight.

A type of bolt with a round head and a square or finned shank under the head, designed for use in wood or materials that require a more secure hold.

A joining process where a non-ferrous filler metal is melted into grooves or as a fillet on the mother metal, without melting the base metal.
