fixed-axis
3.South Pointing Chariots can be classified into fixed-axis wheel system and differential gearing system.
4.THE PROBLEM OF TURNING OF THE BURNABLE EVEN MASS ARCHIMEDES HELICES PLATE AROUND A FRICTION-FREE VERTICAL FIXED AXIS ON A HORIZAONTAL PLANE
7.A new method, that is, describing the fixed-point motion of lower limb taches with Bryant angle, which can bring the rotational axis into correspondence with the movement axis of the body and avoid what will arise from the application of Euler angle to the description, has been introduced in this paper.
9.The aircraft features:compact,high speed,high precision cut and simple,automatic struggle,meter,automatic waste removal,fixed-length features such as automatic parking,admission and the release of volumes of gassing axis used against PVC,CPE,CPP,aluminum foil,paper roll all material cut,packaging and printing industry is the ideal equipment.
