## The pole OB is subjected to the 6004b force at B. Determine (a) the rectangular components of the force; and (b) the angles between the force vector and the coordinate axes. To determine

(a)

The rectangular components of the force.

### Explanation of Solution

Given Information:

Calculation:

The force is directed from point B towards point A. The coordinates of these points are,

A(20,60,0) ftB(0,0,90) ft

The position vector of A relative to B ,

BA=(200)i+(600)j+(090)k =20i+60j90k

The unit vector in the direction of this position vector,

λ= BA| BA |=20i+60j90k 20

To determine

(b)

The angle between force vector and coordinate axes.
