O QUE SIGNIFICA PULLEY EM INGLÊS
Polia
Uma polia é uma roda em um eixo que é projetado para suportar movimento e mudança de direção de um cabo ou cinto ao longo de sua circunferência. As polias são usadas em várias maneiras de levantar cargas, aplicar forças e transmitir energia. Em contextos náuticos, o conjunto de roda, eixo e concha de suporte é referido como um "bloco". Uma polia também é chamada de roldana ou tambor e pode ter uma ranhura entre duas flanges em torno de sua circunferência. O elemento de acionamento de um sistema de polia pode ser uma corda, cabo, correia ou corrente que corre sobre a polia dentro da ranhura. Hero of Alexandria identificou a polia como uma das seis máquinas simples usadas para levantar pesos. As polias são montadas para formar um bloco e equipamento para proporcionar vantagem mecânica para aplicar grandes forças. As polias também são montadas como parte das correias e correntes para transmitir a potência de um eixo giratório para outro.
