What /



is
/ /



strength? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Strength
/ /



is
/ /



the ability of a material to withstand a force applied to it
/ // // // // // // // // // // //




What /



is
/ /



ductility? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Ductility
/ /



is the amount that a material can be deformed.
/ // // // // // // // //




What /



is
/ /



malleability? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Malleability is the ability of a material to
/ // // // // // // //



deform
// /



without
/ /

,/ rupturing. /



/ This /



/ means /



/ that the material can be changed without it breaking
// // // // // // // //




What /



is
/ /



hardness? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Hardness
/ /



is
/ /



the
/ /



ability
/ /



of
/ //



a /



material
/ /



to
/ /



resist
/ /



wear
/ /



and
/ /



abrasion.
/ /



The
/ /



harder the material the harder it is to make a mark on the
/ // // // // // // // // // // // //



surface
//




What /



is
/ /



toughness? - CORRECT ANSWERS(S)✅✅Toughness is the
/ // // // // //

,ability
// /



of
/ //



a /



material
/ /



to
/ /



withstand
/ /



an
/ /



impact without breaking. It is the opposite of brittleness
/ // // // // // // // //




What /



is
/ /



brittleness? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Brittle
/ /



materials
/ /



will
/ /



shatter
/ /



in response to an impact. It is the opposite of toughness
/ // // // // // // // // // //




What is stiffness? - CORRECT ANSWERS(S)✅✅Stiffness is
// // // // // //



the ability of a material to resist bending.
// // // // // // // //




What is the difference between a ferrous and a non-
// // // // // // // // //



ferrous /



alloy? -
/ // /



CORRECT
/ /



ANSWERS(S)✅✅Ferrous
/ /



alloys contain iron. Non ferrous alloys do not.
/ // // // // // // //

are
/ /



the properties of cast iron? - CORRECT ANSWERS(S)✅✅3
/ // // // // // // //



- 3.5% carbon
// // //




Good compressive strength // //




Hard, /



so can be difficult to machine, but suitable for casting
/ // // // // // // // // //




Brittle compared to other ferrous alloys // // // // //




Poor corrosion resistance // //




Low cost //




What /



are
/ /



some
/ /



uses of cast iron? - CORRECT ANSWERS(S)✅✅Anvils
/ // // // // // //




Engineering vices //




Tool beds //




What /



are
/ /



the
/ /



properties
/ /



of
/ /



low
