Expert Solution
Step 1

If a force F is inclined at an angle θ with the horizontal, then the component of force along the horizontal direction is the product of F and cosθ. Similarly, the component of force along the vertical direction is product of F and sinθ.

 

The same force F inclined at angle θ with the horizontal can be represented in cartesian vector form as,

F=Fcosθi+Fsinθj

Here, force vector is F and the direction vectors are i and j.
