2025年1月17日 · Vectors are useful tools for solving two-dimensional problems. Life, however, happens in three dimensions. To expand the use of vectors to more realistic applications, it is necessary to create a framework for describing three-dimensional space.

2022年1月21日 · We will discover how to represent and graph a 3D vector in three dimensions, find its magnitude, product of a scalar, add and subtract vectors, create unit vectors and more. Let’s jump right in and marvel at the importance of vectors.

In this section we will discuss four methods to specify points and vectors in three-dimensional space. The most commonly used method is an extension of two-dimensional rectangular coordinates to three-dimensions.

Topic 04 covers: 1) Describing a position vector; 2) Determining position vectors from given information; 3) Representing a force directed along a line using a position vector; 4) Calculating the magnitude and coordinate direction angles of the resultant force in 3D using position vectors.

This interactive shows the force and position vectors for use in the moment cross product. The position vector is a vector from the moment center to any point on the line of action of the force. Figure 4.4.1.

Components of Vectors in 3D : Unit Vectors along the axes OX , OY, OZ are denoted by i , j , k respectively. OP = OA + AN + NP or OP = ( x i + y j + z k ) is the position vector of variable point P. r or OP = where OA = x , AN = OB = y , NP = OC = z Distance OP = | r | = √(x2 + y2 + z2) Position vectors of given points : A ( a 1, a 2, a 3 )

Vectors are useful tools for solving two-dimensional problems. Life, however, happens in three dimensions. To expand the use of vectors to more realistic applications, it is necessary to create a framework for describing three-dimensional space.
