| Abstract: | Making use of elastic coefficient formula of cylindrical spring and Hooke＇ s law, the formula of the distance of the same point relative to spring fixation before and after deformation of still massive spring at the non-inertial frame is deduced. A mathematical expression of uneven spring deformation is given. The equation of still spring deformation and external force at the ends of spring and the calculation formula of elastic force at any position of spring are both deduced at the non-inertial frame. And the question of elastic force distribution after deformation of still massive spring at the non-inertial frame is discussed. |
