Symmetry

Symmetry. Rotational Symmetry and its Graphic Representation. A pattern is symmetric if a single motif is repeated in space. A wheel is a repeating pattern of spokes; the motif is one spoke. Each ccw rotation through angle f is a symmetry operation which produces similarity .

ME 115 Final Spring 2003 Problem 5 By Luke Saxelby

ME 115 Final Spring 2003 Problem 5 By Luke Saxelby. In order to build this model, I started by drawing the rigid parts first to the proper size and orientation. I then rigidly joined them together. Next, I drew the disk to the proper size and orientation and weight.
