436–438 p. Abstract- We describe the features and reasons for occurrence of the peculiar oscillations in the speed and acceleration of a taut chain passing over a rotating sprocket. With an increase in the number of teeth, these oscillations are smoothed out and disappear in the limiting case of a flat belt drive. Uniform and uniformly accelerated motions are the basic types of mechanical phenomena and are studied in detail in physics courses. The only example of variable-acceleration motion amenable to a simple mathematical description and presented to introductory physics students worldwide is the example of harmonic oscillations. In this paper, we consider the simple instructive case of the jerky motion of a chain passing over a sprocket wheel. A sprocket is a profiled wheel with teeth that mesh with a chain, track, or other perforated or indented material. Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery to transmit rotary... ***______{For Hard Copy, Please visit Library.}________*** Kinematics Sprocket Wheel Kinematics of a chain 530.071 0031-921X RIEBPL Library https://doi.org/10.1119/5.0090382 https://doi.org/10.1119/5.0090382 231106 20231120095556.0
