Possible elements in my opinion from Khurmi Textbook of Machine Design, and Moring and Faires Design of Machine Elements

A machine part subjected to axial compressive force

strut

It has been observed that when a column or a strut is subjected to a compressive load and the load is gradually increased, a stage will reach when the column will be subjected to ultimate load. Beyond this, the column will fail by crushing and the load will be known as

crushing load

If the load is gradually increased, the column will reach a stage, when it will start buckling. The load, at which the column tends to have lateral displacement

buckling load

the ratio of the effective length of the column to the least radius of gyration of the section.

slenderless ratio

crushing stress and young’s modulus for mild steel

330 Mpa, 0.21×10⁶

Sometimes, the columns whose slenderness ratio is more than 80

long columns

Constituent precipitating from a solid solution. Consequences include strength and hardness. Occurs in some metals at ambient temperature after solution heat treatment

Age hardening

Composed of two or more metallic elements

Alloy

The metallic elements added for the purpose of modifying the properties

Alloying elementsAnis

The characteristic of exhibiting different properties when tested in different directions (“with the grain” or “across the grain”)

Anisotropy

Tendency to fracture without appreciable deformation

Brittleness

One which a specimen, supported at both ends as simple beam, is broken by the impact of a falling pendulum

Charpy test

One which a specimen, supported at one end as cantilever beam, is broken by the impact of a falling pendulum

Izod test
