Rotation matrix is a type of transformation matrix that is used to find the new coordinates of a vector after it has been rotated. Understand rotation matrix using solved examples.
9.9 Torque transfer systems : 9.9.1 Any system or device the design of which is capable of transferring or diverting torque from a slower to a faster rotating wheel is not permitted. 9.9.2 Any device which is capable of transferring torque between the principal axes of rotation of the two ...
Multiplying by ii has the effect of rotating numbers 90-degrees, and as you might expect, things only make sense here if we start thinking beyond the number line and in the complex plane. Geometrically, which of the following describes the point i⋅(a+bi)i⋅(a+bi) on the complex ...
