【Abstract】 Screw calculus is used to find the sum of two screws and three formulae are obtained determining the resultant. The formulae can, besides solving the addition of two screws, be extensively applied to such studies as mechanisms, kinematics and statics, and gearing and meshing theories. These applications are illustrated.更多还原
