B A C is the average angle formed by a string passing over the bridge
of a Violin, and the tension acts equally in the direction A B, A C.

[Illustration of angles of the strings.]

Take A C=A B.

From the point B draw B D parallel to A C. And from the point C draw
C D parallel to A B, cutting B D at D.

Join A D.

Then, if a force acting on the point A, in the direction of A B, be
represented in magnitude by the line A B, an equal force acting in the
direction A C will be represented by the line A C, and
