Partyinend alipeline to one and the Belous alleching de the Priced of estilkelion Tof a thing berbulum and also determine the string constant Theory: A string bendulum (also called elastic prodhul.com mestnything thing ) a Hyred obydon show a Pace system where prece of mass is connected to spring so that the moscalling motion contains elements of a simple fendulum as spring. When a string trung is stretched on compressed, the force required to streche the sering is often by Hocke's Law: F = – kx x 45 distance the abreng is stretched on compressed and K is the constant determines the "stiffn # 83 mess of the thing Newton/meter.
