Its true aim is to stir up racial tensions.
These latter lines measure the tensions in the successive portions of string.
The relation between the three forces acting on any particle, viz, the extraneous force and the tensions in the two adjacent portions of the string can be exhibited by means of a triangle of forces; and if the successive triangles be drawn to the same scale they can be fitted together so as to constitute a single force-diagram, as shown in fig.
The tensions in the successive portions of the string are therefore proportional to the respective lengths, and thelinesBH,CK.., are all equal.
The three angles between the tangent planes to the three surfaces of separation at the point 0 are completely determined by the tensions of the b o a three surfaces.
