Question:
To understand Cartesian representations of vectors and how they can be determined from direction and magnitude; to learn how to represent vectors expressed as a product of the component magnitude and the unit direction vectors i
j
and k
; and to learn how to represent a vector component as a function of the angle between the vector and the coordinate axis.
As shown, a pole is subjected to three forces: F
P
and T
The force F
expressed in Cartesian vector form is F i j k N
Force P
has magnitude N
and acts in the direction given by these direction angles: alpha
beta
and gamma
to the x y and z axes, respectively. Force T
lies within the yz
plane, its direction is given by the triangle shown, and its magnitude is N
