I have the answers for the questions but my teacher wants to graph the vector and i want it perfectly beacuse of the angle or vector in the graph.. like in the pictures below
from the 2nd picture it explains the experiment .
I hope you understand me.
Thnak you so much.
The first picture is the qusetions but their answers in the last pictures!! i don't need answers for themwhat i really want is the graph of the vectors like in 2nd or 3rd picturethe experiment about the force ...
what i really want is the graph of the vectors like in 2nd or 3rd picturethe experiment about the force ...

Experiment #2 Name:...... Section:........... Vectors, Force Table Registration number......... Date:..... Mark:.. Results and Discussions:- 1- The aim................ 2- What is the magnitude and direction of the equilibrant force that you found by force table? 3- What is the magnitude and direction of the resultant force that you found by force table? 4- Find the magnitude and the direction of the resultant force by using graphical method? 5- Find the magnitude and the direction of the resultant force by using component method?
Experiment # 2 Vectors, Force Table 2.1 Purpose:- The purpose of this lab experiment is to verify the parallelogram law of vector addition by using a force table. 2.2 Method: A vector is a quantity that possesses both magnitude and direction, examples of vector quantities are velocity, acceleration and force. A vector can be represented by an arrow pointing in the direction of the vector, the length of the line should be proportional to the magnitude of the vector Vectors can be added either graphically or analytically. The sum or resultant of two or more vectors is a single vector which produces the same effect. For example, if two or more forces act at a certain point, their resultant is that force which, if applied at that point, has the same effect as the two separate forces acting together. The equilibrant is defined as the force equal and opposite to the resultant. Suppose we have two vectors A and B with angle 8 between them, as Fig 2.1. مل Fig. 2.1 The resultant of any two or more vectors can be measured by three methods:- a) Graphical Method Two forces are added together by drawing them to scale using a ruler and protractor. The second force (F) is drawn with its tail to the head of the first force (F). The resultant (Fr) is drawn from the tail of F, to the head of F. See Fig 22. Then the magnitude of the resultant can be measured directly from the diagram and converted to the proper force using the chosen scale. The angle can also be measured using the protractor 10

First the two forces are broken into their x and ycomponents using tri FF, come F -F Fa-F;cos F,-F, sin where and are the component of vector F, long x and y direction, respectively, To determine the sum of, and the components are added to put the components of the resultant Fr.-F.com Fy.com F-Fil Fin To complete the milyals, the resultant force must be the form of a magnitude and a direction (ange) So the components of the rose Fans must be combined using the Pythagorean Theorem since the components are at right angles to each other F. where is the angle enclosed by Fx and positive x-axis as revolve counter clockwise c) Experimental Method Two Sorces we applied on the force table by hanging masses over pulleys positioned at certain angles. Then the angle and mass hung over a third pulley me adjusted until it balances the other two forces. This third force is called the equilibrant F.) sunce it is the force which establishes equilibrion. The qualibeant is not the same as the resultat (F) The resultant is the addition of the two fotce. While the 11
equilibrant is equal in magnitude to the resultant, it is in the opposite direction because it balances the resultant (see Figure 2.3). So the equilibrant is the negative of the resultant a Fig. 23 A schematic diagram of a force table 2.3 Equipments:- You will use the following equipments to examine various vector forces in equilibrium Force Table, three pulleys and pulley clamps, three mass hangers, mass set, string, metric ruler, protractor, and one sheet paper. 2.4 Procedure To find the resultant of two forces, a 100g force at 30' and a 200g force at 155". a. Place one pulley at 30and the other at 155". b. On each string that runs over these pulleys, place a mass of 100g at 30° and 2009 at 155° (including hanger-cach hanger has a mass of 50g). c. With a third pulley and masses, balance the forces exerted by the two masses. The forces are balanced when the ring is centered on the central metal peg, To balance the forces, move the third pulley around to find the direction of the balancing force, and then add masses to the third hanger until the ring is centered d. The balancing force obtained in (c) is the equilibrant force. The resultant has the same magnitude as the equilibrant but opposite direction. To determine the direction of the resultant, subtract 180 degrees from the direction of the equilibrant e. Include a graph where you obtain the equilibrant vector using the graphical method. Make sure to label and include direction/magnitude labels and values of each given vector on your graph. When reading your graphical method, the reader ought to be able to see clearly the two vectors given with their 12
respective angles, and the equilibrant vector with its angle. Finally, include the scale that you chose 1. Express each given vector in component notation, add them up and calculate the resultant vector. From your result, express the resultant vector in magnitude and direction. Finally, deduce the equilibrant vector (in magnitude and direction) 13
