  We derive photometric, structural and dynamical evolution-related parameters
of 11 nearby open clusters with ages in the range 70 Myr to 7 Gyr and masses in
the range $\approx400$ \ms to $\approx5 300$ \ms. We search for relations of
structural and evolutionary parameters with age and Galactocentric distance.
The main results for the present sample are: {\em (i)} cluster size correlates
both with age and Galactocentric distance; {\em (ii)} because of size and mass
scaling, core and limiting radii, and core and overall mass correlate; {\em
(iii)} massive ($\rm m\geq1 000$ \ms) and less-massive clusters follow separate
correlation paths on the plane core radius and overall mass; {\em (iv)} MF
slopes of massive clusters are restricted to a narrow range, while those of the
less-massive ones distribute over a wider range. Core and overall MF flattening
is related to the ratio ($\tau$) of age to relaxation time. For large values of
$\tau$ the effects of large-scale mass segregation and low-mass stars
evaporation can be observed in the MFs. In this sense, $\tau$ appears to
characterize the evolutionary state of the clusters. We conclude that
appreciable slope flattenings in the overall MFs of the less-massive clusters
take $\sim6$ times longer to occur than in the core, while in the massive
clusters they take a time $\sim13$ times longer. We investigate cluster
parameters equivalent to those determining the fundamental plane of
ellipticals. These parameters are: overall mass, projected mass density and
core radius. We conclude that in the present sample there is evidence of a
fundamental plane.
