Design Technology Paper 1 0.0 / 5 ? Design Technology: Product DesignMaterials and their applications A2/A-levelAQA Created by: meepmeepsheepCreated on: 27-02-22 11:32 mechanical properties = how a material reacts to an external force 1 of 12 compressive strength = ability to withstand being crushed by pushing forces (compression) 2 of 12 tensile strength = the ability to resist stretching or pulling forces (tension) 3 of 12 bending strength = the ability to resist forces that may bend the material 4 of 12 shear strength = the ability to resist sliding forces on a parallel plane 5 of 12 torsional strength = the ability to withstand twisting forces from applied torsion 6 of 12 hardness = the ability to resist abrasive wear e.g. scratching 7 of 12 toughness = the ability to absorb impact force without fracture 8 of 12 plasticity = the ability to be permanently deformed (shaped) and retain deformed shape 9 of 12 ductility = the ability to be drawn out under tension without cracking, e.g. stretching a material into a wire 10 of 12 malleability = the ability to withstand deformation by compression without cracking - increases with temperature rise 11 of 12 elasticity = the ability to be deformed and then return to the original shape when the force is removed 12 of 12
