Curve E:
This curve appears to be the integral of a sinusoid. It could
therefore represent the total electrical power dissipated as a
function of time for a device through which we pass an alternating
current
Curve F:
This curve could represent the amplitude of oscillation of an
undammed spring which is the suddenly stopped.
Curve G:
This curve could represent the magnitude of a pendulums
displacement from its equilibrium position (assuming the pendulum
begins at maximum displacement).
Curve H:
Charging of a capacitor
Curve I:
Radioactive decay. This curve could represent the number of nuclei
decaying per second from some radioactive source.
Curve J:
Normal distribution: Height or weight
This could also be a resonance curve. The Y axis could be the
amplitude of osciallation and the X axis could represent the
frequency of the input, at the natural frequency we would get a
very high amplitude response.
Curve K:
Curve L:
This curve could represent the fracture toughness of an alloyed
metal, the Y axis representing the fracture toughness and the x -
axis representing the volume fraction of the alloy.
