Target entity: Chebyshev linkage
Context triple: [Pafnuty Chebyshev, notableWork, Chebyshev linkage]
  • A. Tusi couple
    The Tusi couple is a geometric device from medieval Islamic astronomy that generates linear motion from the sum of two circular motions, later influencing Copernican models of planetary motion.
  • B. Chaplygin R
    Chaplygin R is a small satellite impact crater on the Moon located near the larger Chaplygin crater on the lunar far side.
  • C. Varignon’s theorem in statics
    Varignon’s theorem in statics is a fundamental principle stating that the moment of a force about a point equals the sum of the moments of its components about that point, simplifying the analysis of mechanical systems.
  • D. Torqued Ellipses
    Torqued Ellipses is a series of monumental, curving steel sculptures by Richard Serra that immerse viewers in disorienting, spiraling spatial experiences.
