Hardness a fixed height onto a material. This type of hardness is related to elasticity. The device used to take this measurement is known as a scleroscope. Two scales that measures rebound hardness are the Leeb rebound hardness test and Bennett hardness scale. There are five hardening processes: Hall-Petch strengthening, work hardening, solid solution strengthening, precipitation hardening, and martensitic transformation. In solid mechanics, solids generally have three responses to force, depending on the amount of force and the type of material: Strength is a measure of the extent of a material's elastic range, or elastic and plastic ranges together.

101 George Street, The Rocks history of New South Wales. The place possesses a degree of rarity as the first site to be the subject of heritage renovations/reconstructions in the 1970s, when the plans of the Sydney Cove Redevelopment Authority to raze The Rocks for redevelopment were still in place. The place is important in demonstrating the principal characteristics of a class of cultural or natural places/environments in New South Wales. The scale and streetscape character of the Phillip's Foote building is representative of early 19th commercial building in The Rocks as a plain two-storey shop with residence. 101 George Street, The Rocks 101 George
