Activity Week 9: Force Table The objective of this lab is to experiment with the balance of forces occurring for a system in static equilibrium. In this process the vector properties of the forces will be demonstrated. Force Table: A metal ring stands in the middle of the force table. Three strings are attached to this ring and the other end of the each string is tied to a weight hanging on the side of the table. The three strings therefore apply three tensions T, T2 and T3 to the metal ring in three different directions. The tension in each string is simply equal to the hanging weight. The goal is to put the metal ring in static equilibrium by properly orienting the strings so that to the net force is zero. You will express all values with 3 significant figures (SF). Don't forget units. Give me back your copy at the end of the laboratory period. NOTE: We will always set string #1 at the 0 mark of the force table to simplify calculations. Case 1: One unknown force: T3. You know T and T. You're looking for both magnitude and direction of force T3. You will be able to define T3 graphically in this case. Mass 1: 100 Mass 2: Mass 3: NOTE: All masses given must include the mass of the hanger. 100 g ? g M= d. What type of triangle did you create? e. Deduce the magnitude and direction of T3. T3= 0= 60 03 = f. Calculate M, in grams. T= T3= You will obtain tension T3 (both magnitude and direction) so that the ring is in static equilibrium. a. Calculate the magnitude of T and T. T= T= b. What is the direction (angle) for T, and for T2 as defined in the figure. 0= 0= 03 T c. Draw T, Tand 7, using the head to tail method on an x and y graph. A static equilibrium implies that the sum of all vectors leads you back to the starting point. You can also say that T3 is the equilibrant force to T and 7. O h. Final results (N for forces, g for masses, for angles) T= M = M = M = T3 T g. Set up Mass 1, Mass 2 and Mass 3 for the corresponding T, T and T magnitudes and directions. Confirm you results by finding the static equilibrium on your table using the M, you calculated. Be careful to remove the mass of the hanger from each M values. MAKE ME VERIFY. 0 = 0= 03=
