Huynh, Anne June 23, 2008 Ryan Whitmer Meshann Anderson Maria Agusto Jerem Harvey Kieu Tri The Force Table Purpose: The reason for the lab was to learn about the concepts of vector components and vector addition. We observed how a vector is a quantity which has both a magnitude and a direction. Displacement, velocity, acceleration, and force are the vector quantities which we have discussed thus far. Some rules applied in this experiment include the triangle rule or the parallelogram rule which were used to obtain angles between vectors and the x-axis. Summary: In this lab, we used a force table with centering pins. Pulled forces were applied to a ring on the force table by strings passing over pulleys and connected to hanging weights. Initially, the center pin is inserted to hold the equilibrium position. If the pin is removed and the ring does not move, then we know that the forces remain in equilibrium with regards to the angle

Unformatted text preview: (read by looking at the scale on the top surface of the force table) and the weights applied. The three parts of the procedure include finding the reverse vector, demonstrating the equivalence of the effect of a single force to that of its two components forces and lastly, verifying the component method for the addition of three vectors. In the end, our results supported and validated the purpose of the lab exercise. Experimental Errors: We ran into a few minor errors while completing this lab. The more frequents error was in our measurements. There was friction is the wheels which contributed to inaccurate measurements. It was also difficult to get the exact degree on the force table. Ultimately, the calculated error was 0.02% for this lab....
