In case where the ship's launching speed has to be placed under control, drags are usually used. In thin case the drag wires receive tension. And as the result of dynamical analysis of the tension, the tension of the paid-out type drag such as the horseshoe shaped drag is given by the following formula P_<max>=μw+wV^2/<ag> where μ: frictional coefficient between drags and ground w: weight of drag V: Ship's speed at the time when drag begin to act a: Length required for paying out the drag g: Acceleration of gravity While the paid-out type drag model was being pulled at a constant speed, the tension of the drag wire was recorded by means of the oscillograph with the result that the changes in tension and the maximum tension of the drag wire in strict agreement with the result of the above dynamical analysis.
