WebSep 1, 2024 · The rotated coordinate axes have unit vectors ˆi′ and ˆj′ .The angle θ is known as the angle of rotation (Figure 12.4.5 ). We may write the new unit vectors in terms of the original ones. ˆi′ = cosθˆi + sinθˆj. ˆj′ = − sinθˆi + cosθˆj. Figure 12.4.5: Relationship between the old and new coordinate planes.

Web1. The simplest way to measure rotation angle and angular velocity is to use Stepper motor. Either it is unipolar or bipolar stepper motor (Bi-polar stepper motor is little difficult from unipolar s/m). The simplest method: The Unipolar stepper motor has five wires (Mostly used in 5" Floppy Drive) one for ground and other 4 wires are used to ...
