Science
A component of all matter
atom
Are versatile engineering materials, including such common items as brick, porcelain, glass, and cement
Ceramic
Describes a force applied to an object that attempts to squash the object
compression
The property of a material to return its original shape after a distorting force has been removed
Elastic
Designing for bodily needs of a given working environment
Ergonomics
When electrons flow (electric current) first in one direction and then flows back again and continue this back and forth motion
Alternating Current (AC)
Metals which contain primarily iron with small proportions of other materials
Ferrous metals
Describes the amount of grip a material has when sliding in contact with another surface
Friction
Able to be stretched without failure
Ductile
Drawing where an object is fully described by projecting a series of related views from various viewing positions (above, front on, side on)
Orthogonal
the atoms form into definite repeating patterns or ‘lattice’ structures
Crystalline
An alloy of iron and carbon
Steel
The property of a material to resist penetration or scratching when brought into contact with another material
Hardness
A measurement of a materials mass per unit volume
Density
An initial version of an item, often produced at the development stage of a product
Prototype
The amount of matter that is contained within that object
Mass
They contain two or more different substances, which are combined to form a homogeneous product
Composite
Describes a force applied to an object that attempts to stretch the object
Tension
Describes how a material reacts to external changes
Stability
The force applied to overcome the resistance
Effort
Lies at the centre of the atom, consisting of protons and neutrons
Nucleus
A process used to coat a base material (normally steel) with a thin coating of zinc alloy, a corrosion resistant metal
Galvanising
A state in which all forces are balanced
Equalibrium
The ability of a material to be shaped without fracturing
Ductility
A pivot point that allows a body to freely rotate about it
Fulcrum
