If all masses centered at a particular point P, these distance from this from this P; not P; this O centered at O is distance is capital L from the point of suspension ok, then this then this will be equivalent plus simple pendulum. All mass concentrate at this point P distance is capital L from and this L is L is square root of k square by l plus l; small l.
जर सगळे वस्तुमान हे बिंदू O मध्ये सामावले असेल तर तिथपासून चे अंतर मोजले तर ते L इतके आहे.
