material to be strong enough to support the load
, ◉ In mechanical properties, what is stress? Answer: Response to
external forces
◉ In mechanical properties, what is shear stress? Answer: force
parallel to the surface
◉ In mechanical properties, what is tension? Answer: it is the pulling
apart
◉ In mechanical properties, what is elasticity? Answer: it is the
ability of a structure or object to return to its normal shape
◉ In mechanical properties, what is compression? Answer: it
measures the load pushing in against the structure
◉ In mechanical properties, what is torsion? Answer: It is the
twisting force against the structure
◉ In mechanical properties, what is ductility? Answer: it is a large
deformation before a structure ruptures
◉ In mechanical properties, what is fracture toughness? Answer: Its
resists cracking
◉ In mechanical properties, what is fatigue? Answer: is it the static
load over a long period or a dynamic load whn a machine is engaged
