Now, applying the trigonometric method to find each component
cos = and sin =
− = cos
= − 800 kos 35
= −655
So
= sin
= 800 sin 35
= + 459
The vector components FR are thus,
Fx = -(655 N) i
Fy = +(459 N) j
and we can write F in the form
FR = -(655 N) i + (459 N) j
Example 2.6
A worker pulls with a force of 300 N on a rope as shown in Figure 2.16 (a). Determine the
horizontal and vertical components of the force exerted by the rope at point A.
