Magnitude & Unit Vectors

Vector 1:

Vector 2:

Vector 3:

Vector 4:

Vector 5:

Vector 6:

If you enter exactly 3 vectors, you will see a button to insert the resultant unit vectors directly into 3x3 matrix

Vector A:

Vector B:

The dot product calculator will also calculate the angle between A and B.

Parallel component of Force vector F along A:
F_∥ = (F ⋅ u_A) u_A

Perpendicular Component:
F_⊥ = F - F_∥

Magnitude of |F_line| = F ⋅ u_line

Moment about a point: M_o = r x F

Vector A (r):

Vector B (F):

Ex. for calculating moment about an axis. Equivalent to: M_o = u ⋅ (r x F)

Unit vector of the axis

Position vector from axis to any point on the line of action of the force

Force vector
