Define thermal conductivity - The ability of a material to conduct/transfer heat, Define permittivity - The ability of a material to store electrical energy, Name the process which allows fluids to diffuse through a medium without being chemically or physically affected - Permeability, What does the Charpy test measure? Which mechanical property does it fall under? - Impact resistance , toughness, What does the vickers test measure? Which mechanical property does it fall under? - Resistance to permanent indentation , hardness, What mechanical process involves the ability to deform without fracturing? - Ductility, Name a ferrous metal - Cast iron, Steel, Name a non-ferrous metal - All on the periodic table other than iron (aluminium, lithium, copper, zinc, ect), Name the type of polymer that chemically reacts, hard and rigid, stay solid under heat when cured, not reversible. - Thermoset, Define thermoplastic - Resin solid at room temp but when heated is soft and plastic, process is reversible, Name the 3 groups of ceramic products - Whiteware (plate), refractory (insolation) and engineering products (electronics), Define polymers - Made up of many simple molecules that are repeating structural units like building blocks., What is deep drawing? - Moulding metal sheets into intricate shapes by pushing them into a die cavity with a punch., What does ABS stand for  - Acrylonitrile butadiene styrene, What are Van Der Waals Forces? - Weak attractions between molecules caused by temporary fluctuations in electron distribution, which create temporary dipoles., Work out all forces , Work out vertical + horizontal components and resultant force + angle, Define specific heat capacity - Amount of heat required to change a unit mass of a substance by 1 unit of temperature. (J/KG/℃), Define latent heat - Amount of energy needed to change the state of a material., Explain how thermal expansion affects overhead electrical cables - Overhead electrical cables hand low in the summer. Without this allowance, as they contract in the winter they could break., What is anthropometric data? - Data on human body size, What are the 6 R's? - Rethink, Refuse, Reduce, Reuse, Recycle, Repair, What is quality control? - Checks products for defects towards the end of the process, What is quality assurance? - Preventative process used to prevent defects and focusses on the production rather than product, What is mechatronics? - Control of movement with an electrical input, What is a maintenance engineers role? - Communicating issues with managers, cleaning and performing routine maintenance, What is standard deviation? - Measurement of data spread for a set of values, What is reliability centred maintenance? - Non-destructive methods of inspection (MTBF), What is SLA? - Stereolithography is a 3D printing technology that uses a laser to cure and harden layers of liquid resin into solid objects.,
