    Obviously, the OA up-pull force and the OB up-pull force are combined to balance with gravity.

    f(oa)=

    f(ob)=

    How have I ever seen this question.

    oa, ob net force is equal to gravity, parallelogram is fine:

    foa=sin60 *f=

    fob=sin30 *f=

    n-mgcosθ=0

    f-mgsinθ-f=ma

    f= n can solve this equation, and draw it by yourself by analyzing the physical force of the branch in the bucket.

    It depends on the situation and amuses the game 1Numerical representation: The greater the absolute value, the greater the force For example, 30n, 9n, -50n are -50n maximum, then 30n, and finally 9n

    The force is a vector, the plus or minus signs in front of it only represent the direction, and the numbers behind the potato brigade are its true size. 2.Representation in Force Analysis:

    This is more intuitive, the longer those arrows that represent the force, the greater the force. The pull force of the rope is given in some questions, and you can also understand it as f.

    There are numbers and diagrams for representation. Figure: f=20n Figure:

    1.Diagram of force 2Schematic diagram of force They are similar to each other, but the difference between them is the value of the specific magnitude of the latter's powerlessness.

    The illustrated representation of the force is a line segment with an arrow, if the force is 20n, you can define one centimeter for 5n, and then draw 4 centimeters, the square of the arrow is the direction of the force, the root of the line segment is the point of action of the force, and the general noise is the force point or center of gravity of the stressed object (this is often used when doing problems).

    The magnitude of the pulling force is named after the person named Newton.

    Its symbol is represented by a capital "n".

    Hope it helps.

    Of course, "n" is used, and the unit of force is Newton.

    f denotes the pulling force of the object and f denotes the frictional force.
