Analysis: The result of the experiment show the percentages errors of the polygon method of trial 1 and trial 2 are below 5% error, in the case that the vector are well drawn and the data was accurately collected from the force table. It also show percentage errors of the component method of trial 1 and 2 are below 5%.
The experiment used a force table to determine the angle of each vector by placing different weight to the super pulleys. After placing each weight to the corresponding pulley, by trial and error, we were able to find the angles of each corresponding weight. After gathering the necessary data needed to solve for the theoretical value of the resultant, two methods are used to find the value of the resultant. First is by using the graphical method or to be more specific by using the polygon method. In the polygon method more than two forces may be added at the same time. The arrows representing the forces are connected head-to-tail. The next method is the component method which is more in the analysis of the given problem rather than using a graphical chart. Each force had its own x and y component and can be solve by using Fx = Fcos and Fy = Fsin. The resultant may be determined by adding all the components along the x-axis and all the components along the y-axis. Then by using the Pythagorean Theorem, we can find the magnitude of the resultant. Then the direction can be solved by using tan.
Conclusion:
The objective of the experiment is to determine the resultant force by using the graphical method and the analytical method and to be familiar to the difference of scalar from vector. Scalars are quantities containing the magnitude only while vector contains the magnitude and also the direction. After performing the experiment, I can therefore conclude that the resultant for a set of vectors, acts like a balancing force for the system wherein the forces of the given vectors act on. Finding the correct value for the resultant would be
