Question

ection: O Materials Needed: Vector table with accompanying equipment (metal ring with three strings tied to it, three metal hooks, various masses that can connect to hooks) First, watch what happens when two masses are connected to the ring. Think of the force being exerted by the string on the ring as a vector that points in the direction of the string 1) The ring is in equilibrium when two identical masses are attached, and the strings point in opposite directions. Why? 2) Next, we are going to attach three masses to the ring. The strings will be placed with their angles as shown. Is it still possible to create a situation where the ring is at equilibrium? If so, what should the masses be? (Hint: Start by putting your answer to #1 in equation form, and then set up this one the same way.) When you have an answer raise your hand and we will set up the apparatus based on your instructions to see if it works. Fa F3
