Direction of resultant force

  1. May 1, 2016 #1
    1. The problem statement, all variables and given/known data
    i am confused about the direction of resultant force . in the working ,it's clear that the author taking to the right as positive ,
    for the force component along x-axis , we have -Fx , but , in the calclulation , we gt positive 32230N , so the resultant force of x-component is to the left(32230N ) , am i correct ?

    2. Relevant equations


    3. The attempt at a solution

    The author is taking Fx to be positive if the force is pointing is the negative x direction.

    ia my idea correct / the resultant force act to the left ?

    In vector terms, the x component of the force ##\vec{F}## is taken to be ##-F_x\vec{i}_x##, where ##\vec{i}_x## is the unit vector in the positive x direction.

    is my idea correct ? the resultant force act to the left ?

    Yes. It is positive to the left.
