    physics question

    [IMG]file:///C:/Users/91621/AppData/Local/Temp/moz-screenshot.png[/IMG]1.Consider an object with several forces acted on it from various directions, as shown in the diagram below. Calculate the resultant forces in the x and y directions.

    HI

    Your diagram is not very clear , i can only see the arrows .
    Btw ,

    I am sure you know that you will need to resolve all the forces horizontally and vertically .

    For horizontals , resolve all forces horizontally , then find the resultant force (Big minus small) ,

    Do the same thing to vertical .

    when you resolve , you also need to consider the direction of the forces , as to whether its going to the left or right side , up or down .

    Give it a shot .

    further clarification

    Heyz..thanks for replying!

    I knew that i need to resolve the forces but i dont get the right value.
    could u write out the working specifically?
    So sorry for the trouble!

    See the diagram i attached . I know its terrible .

    I cant see what are the forces in your diagram so i use F1 , ... to denote them .

    For horizontals , forces going to the left are

    F_1\cos 60 and F_3

    To right : F_2\cos 60 and F_4\cos 45

    Find which is greater , then take the difference between the right side and LS forces .

    DO the same for vertical .
