Question

In this exercise, you will begin with a system that is not in equilibrium, predict the mag nitude and direction of a force necessary to place it in equilibrium. You will also use second graphical technique to reach the same conchusion. Measurements around the side of the table mark 360 degrees. We will set 0 degrees as our positive x axis, and attach pulleys as directed. In each of the combinations shown below, three pulleys are attached to a center ring, with the specified masses and angles. Combination #1 Combination #2 Pulley #1 #2 #3 Mass (g)Angle () Mass (g) A Angle () 150 110 100 70 150 200 100 150 90 135 For each combination shown in the table: . Draw a force diagram for the center ring. . Calculate the magnitude and direction of the resultant force (net force) on the ring Note that the tension in each string is equal to the weight of the mass hanging over the pulley. Show your work for all three combinations. . Record your results for each combination in a table such as the one shown on the next page. Table of predicted values: Comb ination i pute d#7G-237owetr 0.1,, Pulley 1 Pulley 2 Pulley 3 Resultant (net force) Combination 2 mass (kg) Theta (o)|Force (NTF,(NTAIN) 01001 rnass (kg) | Theta (0) | Force (N) | F, (N) mass (kg) Theta () Force (N) FNF (N)y ert A (N) Pulley 1 Pulley 2 Pulley 3 Resultant (net force) 2.00 .100 10 For each of the combinations of vectors. you also now determine the resultant force graphically. Make a scale drawing to graphically add the three vectors using the tip-to-tail method. From this graphical method, determine the weight and direction a 4th pulley would need to have to balance it. Next calculate algebraically from your table what the x and y components of a 4th pulley would need to be to put the system in equilibrium

I am in a intro engineering physics and having issues with this classwork for our lab.... the values are given in the table.thank u
