. Record the results.B)Analytical: Compute the magnitudes of Fxand Fyby using the Component Method. Record the results.C)Experimental: The force of 320 g is equal to that due to a suspended mass of 300 grams. The Equilibrant Vector is the force vector of equal magnitude, but opposite in direction to the Resultant (i.e. E= -R). The Equilibrant is therefore equal to a suspended mass of 300 grams at the 40+180 = 220º angle. On the force table, clamp a pulley at 220º and hang a mass of 300-gram. Now attach two pulleys, one at 0º and the other at 90º (the X- and Y-components), and add weights to them until they balance the equilibrant force. Equilibrium is seen when the ring in the center of the force table is centered. The two forces are the X- and Y- components of the original force. Record them in the Data Table.2)VECTOR ADDITION: Find the sum of two forces: 100 g at 30ºand 200 g at 120º, by:A) Graphical Method: Make the X- and Y-axes. Use a scale of 25 g = 1.0 cm. Draw arrows of appropriate lengths at 30º and 120º, both starting from the origin. Add them using the Parallelogram method. Measurethe length and angle of the resultant. Convert length to vector magnitude using the scale used to draw the vectors. Record the results in the Data Table. B) Analytical Method: Compute the sum of the two vectors by using the Component Method as well as the Triangle Method. Record the results in the Data Table. C) Experimental method: Clamp two pulleys at the 30º and 120º positions and suspend masses of 100 g and 200 g on them respectively. Now find the Equilibrant by clampinga pulley at an angle 180 plus the angle found by the component method. Attach enough mass to this third pulley to balance the system. If needed, adjust the position of the pulley. The magnitude and position of the equilibrant is thus found. The resultant of the two forces has the same magnitude, and opposite direction to the equilibrant. Note this in the Data Table.3)VECTOR ADDITION: In addition to the two forces of procedure 2, add a third force = 150 g at 230º. Find the vector sum by the Graphical, Component and Experimental methods, and record in the Data Table. Use a scale of 25 g = 1.0 cm for the graphical method.CALCULATIONSShow your calculations for the analytic method and the method of components.
