Model Of A Mechanical Clock Escapement, John Wagner, David Moline, Eugene Vold

Publications

The mechanical tower clock originated in Europe during the 14th century to sound hourly bells and later display hands on a dial. An important innovation was the escapement mechanism, which converts stored energy into oscillatory motion for fixed time intervals through the pendulum swing. Previous work has modeled the escapement mechanism in terms of inelastic and elastic collisions. We derive and experimentally verify a theoretical model in terms of impulsive differential equations for the Graham escapement mechanism in a Seth Thomas tower clock. The model offers insight into the clock’s mechanical behavior and the functionality of the deadbeat escapement mechanism.

On The Stability Of A Microstructure Model, Mihhail Berezovski, Arkadi Berezovski

Publications

Abstract

The asymptotic stability of solutions of the Mindlin-type microstructure model for solids is analyzed in the paper. It is shown that short waves are asymptotically stable even in the case of a weakly non-convex free energy dependence on microdeformation.

Research highlights

The Mindlin-type microstructure model cannot describe properly short wave propagation in laminates. A modified Mindlin-type microstructure model with weakly non-convex free energy resolves this discrepancy. It is shown that the improved model with weakly non-convex free energy is asymptotically stable for short waves.

Open-Ended Project Learning Experience In Graphical Communication, Lulu Sun, Christopher Grant

Publications

This paper includes the implementation of Bloom’s taxonomy in the introduction to graphical communication course and shows how students are moved up Bloom’s taxonomy by changing previous guided individual final project to open-ended projects. Instead of following the instructor’s direction to complete the model design, students are required to research the product they want to design, and build the model by themselves. The open-ended projects enable and challenge students to work on higher level of Bloom’s taxonomy by emphasizing design creativity, exploring real engineering design problem, and enhancing their oral and written skills.
