can someone help with this?

The script needs to

• accepts any number (determined by the program user at run-time) of user-input 2-D force vectors (in component form, with x-, y- magnitudes AND force application point);
• You might ask the user how many vectors will be input (which is easier to code), or
• You can use a signaling mechanism - for example, ask the user whether there are more vectors to input, and continue if there is an affirmative response (which is more interesting and/or user-friendly).
• accepts the x, y coordinates of a reference point within the defined square space;
• calculates the equivalent force/couple system at the reference point, due to the applied forces at the true application points

test case:

Force one: (25, 25) pounds at location (10, 5)

Force two: (-40, 5) pounds at location (4, 7)

Force three: (20, -10) pounds at location (3, 2)

Reference point: (5, 5)

The script will be graded for

1. Adherence to directions;
2. User-friendliness of input and output;
3. Use of Matlab output functions “disp” and “fprintf” to make the output well-understandable by the script user, and
4. Clear, correct and understandable input statement prompts, and
5. Suppression of all unnecessary output values and
6. Adequate responses so that the user understands what user actions have been incorrectly done
7. Correctness of the result when I run it for my own separate test case;
8. Good programming practice, including proper documentation of the completed m-file
9. Good practice includes use of whitespace to make the code readable, and
10. Documentation includes sufficient comment statements to
11. allow a human reader to understand well the intent and method of the script and
12. allow me to know who wrote it and when, and what the variable names represent

the script is:

ThemeCopy

n_vectors = input("How many vectors would you like to input? "); %Initial inputs

referencex = input("What is the x-value of the reference point? ");

referencey = input("What is the y-value of the reference point? ");

sum_Fx = 0; %Defining variables that will be used later

sum_Fy = 0;

moment = 0;

for total = 1:n_vectors %For loop makes the program ask for the desired number of vectors

xi = input("What is the horizontal component of the vector? ");%Inputs for the Forces, one at a time

yj = input("What is the vertical component of the vector? ");

x = input("What is the x-value of the application point? ");

y = input("What is the y-value of the application point? ");

rx = x - referencex; %Finds the relative position of the vector to the reference point

ry = y - referencey;

sum_Fx = sum_Fx + xi; %Sums each vector and moment together as the loop continues

sum_Fy = sum_Fy + yj;

moment = moment + xi*ry - yj*ry;

end

fprintf("The sum of the forces is %.2f i and %.2f j",sum_Fx,sum_Fy) %Display statements for the desired information

fprintf("The moment about the reference point is: %.2f k",moment)

For some reason I am geting the result of: 180

I should be getting a result of: 280

Can you help?

What were your inputs? Are you sure your equation is correct?
