PRODUCT DESIGN Paper 1 Technical
Principles Correct Questions and
Answers (Latest Update)
100% Pass
Mechanical Properties (m) - ANSWER-associated with how a material reacts to an
external force
physical properties (P) - ANSWER-associated with the actual make-up or structure
of the material
compressive strength (Mechanical) - ANSWER-the ability to withstand being
crushed or shortened by pushing forces (compression)
tensile strength (mechanical) - ANSWER-the ability to resist stretching or pulling
forces (tension)
Bending strength (mechanical) - ANSWER-the ability to resist forces that may bend
the material
shear strength (m) - ANSWER-the ability to resist sliding forces on a parallel plane
, Torsional strength (m) - ANSWER-the ability to withstand twisting forces from
applied torque or torsion
Hardness (m) - ANSWER-the ability to resist abrasive wear such as scratching,
surface indentation or cutting
toughness (m) - ANSWER-the ability to absorb impact force without fracture
Plasticity (m) - ANSWER-the ability to be permanently deformed (shaped) and
retain the deformed shape
Ductility (m) - ANSWER-the ability to be drawn out under tension, reducing the
cross-sectional area without cracking, for example stretching a material into a wire
Malleability (m) - ANSWER-the ability to withstand deformation by compression
without cracking. Malleability increases with a rise in temperature
Elasticity (m) - ANSWER-the ability to be deformed and then return to the original
shape when the force is removed
Electrical conductor (p) - ANSWER-allows the flow of electrical current through the
material. A good conductor gives very little resistance to the flow of change.
An electrical property.
