An equilateral triangle PQR of side 60mm inscribed in a circle rolls without slipping along a straight line at 30 degrees to the horizontal. Trace the path of vertices "P, Q, and R" for one complete revolution. Assume initial position of vertex 'P' is in contact with the horizontal line (ie, tangent line).
