This applet simulates the motion of a string of length , mass , and tension (units of the international system of measurement) fixed at its ends. The string is decomposed into equally displaced points and it is assumed that its motion is only transversal (no longitudinal compones computed). Furthermore, the amplitude of oscillation is supposed to be sufficiently small in order to simplify the computation of the transverse component of acceleration, and the motion is assumed to be uniformly accelerated during a sufficiently small time interval (here ).
