Hawkins Electrical Guide, Vol 7, by Nehemiah Hawkins—A ... 2,123. —Vectors. A vector is defined as: a line, conceived to have both a fixed length and a fixed direction in space, but no fixed position.Thus A and B are lines, each having a fixed length, but no fixed direction. By adding an arrow head the direction is fixed and the line becomes a vector, as for example vector C. The fixed length is usually taken to represent a definite force, thus ...
