Energy stored within elastic limit is
toughness
resilience
modulus of elasticity
Young's Modulus is measure of
hardness
stiffness
ductility
strength
% elongation is
measure of malleability
measure of hardness
measure of ductility
all of these
strength of the material depends on
load applied on the material
shape & size of the component
both the options are correct
none of the options are correct
