Homework Statement


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 ?

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

what do you mean ?
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.
