[SOLVED] Rotational equilibrium 1. The problem statement, all variables and given/known data This isn't actually a problem, but a portion of our latest lab assignment. There is a pole with 3 hooks in it, one in the center at the top and two at varying distances on the bottom. The pole is hanging from a ringstand by the top hook. the two hooks on the bottom are distances of 20cm(left) and 80cm(right). We were required to add weights to each side until the pole reached a point of rotational equilibrium. once equilibrium was reached the left side had 131.43g of weights and the right side had 36.32g of weights, with this information we are asked to determine the mass of the hanging pole. so far i haven't found out how to apply the given information, if anyone has any ideas help would be much appreciated.
