The paper deals with the reconfiguration analysis of the single-loop variable degree-of-freedom (DOF) RRRRS mechanism composed of five links connected by four revolute (R) joints and one spherical (S) joint. The mechanism may show two modes of motion: one-DOF and two-DOF motion. In the paper. a classical vector procedure is used to obtain the quartic motion equation (QME) that allows ... https://unitedssports.shop/product-category/figure-skating-clothing-tights/
