1A60.20scaling model for biological systemsAJP 45(5),498A wood "cow" with barely adequate legs stands and another scaled up by a factor of 5 collapses.
1A60.22scaling - zoological domainAJP 50(1),72The fundamentals of scaling in the zoological domain covering many animal characteristics.
1A60.302:1 scalingPIRA 1000
1A60.302:1 scalingDisc 08-07"Bridges" of the same geometry are scaled in every dimension by 2:1. Masses placed in the center of the bridges are also scaled 2:1.
1A60.40scaling cubePIRA 1000
1A60.40scaling cube1A60.40A large cube made up of 27 smaller ones is painted black on the outside. Knock the stack apart and show the increase in surface area by the preponderance of unpainted surfaces.
1A60.40scaling cubeDisc 14-16Cut a cube painted black into 27 smaller cube. When dismantled, the unpainted surfaces show the increase in surface area.
