A wire of negligible mass and length l is stretched between two fixed points P and Q. The wire suffers from a tension T when a mass m is attached to the wire. Distance of this mass from fix point P is a and from Q is b. The attachment of mass to the stretched wire sets it into oscillations of small amplitude. Since the amplitude is small, the transverse movement of R is small so the change in length of the wire can be ignored. Thus tension in the wire can be taken as practically same as T itself. The time period of linear vibratory motion of the mass can be given by T=2πω, where ω is a constant of SHM. Angular frequency of SHM of mass m is |
