Please help me, I have already converted the mass in kg and calculated the forces. The hanger that will balance the other two is vector C. Let me know if there's any missing information!
calculations Table vectors mass ( kg) Direction force ( N ) 0. 15 kg 0.35 kg 210 3.43 N 0. 4 kq 1150 3.92 10 Using vector addition, calculate the magnitude and direction of the resultant force R. - A + B. Record all directions as positive angles between 0' and 360. Using strings, weight hangers, and masses, set up forces A and B on the force table at the proper angles and magnitudes. (Remember that the hangers themselves have a mass of 50 grams.) Adjust the mass on the third hanger and its angle until its force balances the other two. This is the equilibrant force that balances R,. Record the magnitude, in both grams and Newtons, and the direction of the equilibrant in a data table like the one illustrated below. Repeat the above procedure for one other vector sum: R. = A + C. Resultant Vector The Equilibrant Vector Magnitude Direction R1 = A +B R. = A + C Points on technique: 1) The force table is balanced when the ring is centered on the center pin. 2) Make sure that the strings are all directed toward the center pin when the force table is balanced. 3) Friction in the pulleys may prevent the ring from moving when small masses are added or subtracted. Try plucking the ring upwards slightly when adding mass to overcome this "stickiness" in the pulleys. Calculations Include your calculations of the resultant forces for both vector sums in your lab report. You may write them in by hand. However, you must show all steps of all the calculations in a neat and orderly fashion. Use the component method of vector addition, but present your final results in terms of angles between 0 and 360. Include a vector diagram for each of the four problems as well. Analysis Compile all of your experimental and calculated results in a data table like the one shown below. Be sure to give the proper units for your results. In particular, remember that force is measured in Newtons, Also, recall that the equilibrant angle is not the same as the resultant angle - they differ by 180 Resultant Vector Experimental Equilibrant Calculated Resultant Magnitude Direction Magnitude Direction R, = A +B R = A + C Calculate the percent error between the magnitude of the experimental equilibrant and the magnitude of the calculated resultant for both vector sums. Comment on the agreement between your calculated angles and your measured angles (remember to account for the 180 difference). Now think about some possible sources of error. What are your measurement uncertainties? Give estimates for them. What are some possible systematic errors? How significant do you think they are? You don't have to give numerical estimates for these, but include some thoughts on how they would likely affect your results
