Is the direction of resultant force to the left in this problem?

Click For Summary
SUMMARY

The discussion confirms that the resultant force in the given problem acts to the left, with a magnitude of 32230N. The author initially defines the positive direction as to the right, leading to confusion regarding the x-component of the force, denoted as -Fx. The consensus among participants is that the resultant force, calculated as positive 32230N, indeed indicates a leftward direction.

PREREQUISITES
  • Understanding of vector components in physics
  • Familiarity with force direction conventions
  • Basic knowledge of Newton's laws of motion
  • Ability to interpret force diagrams
NEXT STEPS
  • Study vector addition and resultant forces in physics

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.

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

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.
