closed chain

• Término utilizado en química y física para describir una estructura molecular en la que los átomos están unidos formando un anillo o bucle, dando lugar a una disposición cíclica en lugar de una cadena abierta.

A term used in chemistry and physics to describe a molecular structure where atoms are connected in a ring or loop, forming a cyclic arrangement rather than an open chain.

1. Closed kinematic chainC1formal

   A mechanical system where the links and joints form a closed loop, meaning the end of the chain is connected back to its base.

   • Robotic arms often use a closed chain design for increased stability.
   • The bicycle frame is an example of a closed chain structure.
   • Engineers analyzed the closed chain mechanism to reduce vibration.

2. Closed chemical chainC2formal

   A molecular structure where atoms are arranged in a ring or cycle, such as in cyclic compounds.
