Documentation(info = "<html>\n<p>\nThis is a connector for 1-dim. rotational mechanical systems and models which represents\na mechanical flange of a shaft. The following variables are defined in this connector:\n</p>\n\n<blockquote><pre>\nphi: Absolute rotation angle of the shaft flange in [rad].\ntau: Cut-torque in the shaft flange in [Nm].\n</pre></blockquote>\n\n<p>\nThere is a second connector for flanges:\n<a href=\"modelica://Modelica.Mechanics.Rotational.Interfaces.Flange_a\">Flange_a</a>.\nThe connectors\nFlange_a and Flange_b are completely identical. There is only a difference\nin the icons, in order to easier identify a flange variable in a diagram.\nFor a discussion on the actual direction of the cut-torque tau and\nof the rotation angle, see section\n<a href=\"modelica://Modelica.Mechanics.Rotational.UsersGuide.SignConventions\">Sign Conventions</a>\nin the user's guide of Rotational.\n</p>\n\n<p>\nIf needed, the absolute angular velocity w and the\nabsolute angular acceleration a of the flange can be determined by\ndifferentiation of the flange angle phi:\n</p>\n\n<blockquote><pre>\nw = der(phi);\na = der(w);\n</pre></blockquote>\n</html>"),
