can someone explain page 2 please
PHYC130 Force vectors and equilibrium. Please use blue ink to complete. 1. Use the following vectors: A = 4.50 N at 0, B = 3.50 N at 120, and for vector C, you choose! Enter your values, with units, specified to 0.1 N and 10: a. Magnitude (between 3.20 and 3.60 N): my ICI = 3.00 N b. Angle relative to the +x direction (1910 to 2069): my Angle Oc = 209 2. From your scaled diagram on graph paper, what is your measured angle and direction of the vector Egraph that brings the system into equilibrium... a. ...As a magnitude and direction: (Show your conversion from measured length to Newtons here. Don't forget units!) 6. 5 amx . 02 VE 1.63 N Measured Egraph = 1.63/ at angle OE = _261.2 b. ...As (x, y) components: Egraph = Co . 25 - 1. 61 ) N. 3a. Calculate and write down the vectors A, B, and C in (x, y) components: A = ( * # 4. 5, 0 )N. B = (-1.7 , 3.0 ) N. C = (-2-62 _, - 1 45 ) N. b. Therefore, find the components of Eth = -(A+B+C): Eth = ( -0, 18 - 1, 55 ) N. c. Convert this to a magnitude and direction. Show your work: I E 1 = J E x + Ey ? > QE = tan- ( 1. 530 ) - 83. 7 7 / IET = VO. 18+ (- 1. 55)'s 1. 560, + 180 Theoretical Eth = 1.560 N=1.7% at angle OF = 263.38 . 4. Finally, if your experimental vector Eth from the force table differes from the theoretical calculation, provide it here: Experimental Eexo = 2.04 at angle OF = 263Questions Q1. If you only had the original 3 mass-pulley systems, what is the smallest number of changes (to masses and angles) required to bring the system into equilibrium. (If you have time, remove the 4" pulley and try it for yourself!). Explain your answer in words, no calculations needed. Well, If we have only 3 values , there will be changes to masses and angles Q2. If a manic lab instructor were to set up the experiment with 5 or more mass-pulley systems pulling on the ring, explain (in words, with a diagram if you wish) why it would still only ever take one additional pulley to bring the system back into equilibrium. Q3. In this lab, you computed forces on the ring using a convenient value of g-10.0 m/s/s. a. If you had used a more accurate value for g, which aspects of your vector diagram would change? What would remain the same? b. If you performed this same experiment on Mars (g~3.4 m/s'), would equilibrium still be achieved with the same set of masses on the 4 pulleys?
