Deformation Pillows
Description: A two-part diagram illustrating a beam's behavior. The top section shows a straight beam supported at both ends with arrows indicating a uniform downward load. A horizontal double-headed arrow denotes the beam's length. The bottom section shows the same beam deformed downwards in a curve due to the load, with a vertical arrow indicating deflection.
Description: A schematic diagram illustrating the calculation of deformation for a truss structure. It begins with a visual representation of the truss with labeled points A, B, C, D, E, F, and P, along with dimensions and reaction forces RyA and RyP. The diagram proceeds to show a 'Free Body Diagram' followed by equations for moment and force equilibrium, and finally, the formula for deformation: \"delta = F / A\".
Description: Rendered on a deep dark background, this artwork presents a coffee mug and a donut side by side, joined by the symbol ≅, both of genus 1, showing that shape is what survives continuous deformation. With Analysis Situs (1895), Henri Poincaré laid the foundations of topology, the study of properties preserved under continuous deformation. To a topologist, a mug and a donut are the same shape: both have one hole. A gift idea for mathematicians, math teachers and engineers, and a quiet statement piece for a study, classroom or office wall.
