3D Simulator of a Rolling Baton on Cylindrical Surfaces
Summary form only given. We make physical analysis of a baton rolling on cylindrical surfaces and then present a 3D simulator which helps us design actual surfaces to be used for a physical performance and for an interactive entertainment system.
Geometric Visual Instruments Based on Object Rolling
If some object can be manipulated using a part of a body, especially, using hands, to create a sequence of aesthetically or geometrically attractive visual patterns, we call it the visual instrument. In this paper, we present visual instruments based on rolling objects on geometric surfaces. First, we present visual instruments that use line segments (or physically, batons) and geometric surfaces such as a cylinder, a globe, and a sequence of truncated cylindrical surfaces on which to roll the batons. We also present the visual instrument called the “gourds”, which are made of some circular arcs. We made simulation for visualizing tempo-spatial patterns and roulettes the instruments create. Through construction of the visual instruments and their manipulation, we have confirmed that they have a high potential for use in manipulative visual performance and play.
The Ultimate Flat Tire
The Problem Suppose a bicycle has square wheels. How can a roadbed be designed so that the ride is smooth, in the sense that the seat of the bike stays horizontal? History The problem was first considered and solved by G. B. Robison in 1960. In 1992 Leon Hall and Stan Wagon investigated other possibilities for shapes of wheels. The first square-wheel bike at Macalester was installed in 1998 and was featured in many television and newspaper pieces, including Ripley’s Believe It Or Not. The new, improved model was installed in 2004. What Is It Good For? Round pieces of wood (quarter-circles) have been found near the sites of Egyptian pyramids and it has been suggested that they were used as a road bed in roughly the shape as the one here, so that large blocks of stone could be moved efficiently. The Answer Each arch of the road is an inverted catenary, the curve one gets by just dropping a piece of chain or rope while holding its ends. Derivation of the Solution Intending to build a model of our solution (using a tricycle to improve stability), we first noted that a commercially available tricycle could be modified slightly so that the distance between its front and rear axles was exactly 42 inches. The roadbed would be a series of arches, and we decided to have three arches span the wheelbase, so that each arch would have a horizontal span of 14 inches.
