Question

AB is a uniform rod of mass 50N. It is divided in to 4 equal parts by the points P, Q and R. The rod is suspended by A and B by 2 strings such that it stays horizontally. 15N and 20N are hung at P and R respectively. Find the tension of the 2 strings. Later, the 20N was removed from R and was replaced by a w weight. At that instance, the tensions of the 2 strings became equal. find w
