The parallel lines of CB in A intersect with the vertical lines at D, so the lengths of AD, DC and CA are the magnitude of the pulling force in three directions (in proportion).

The distance from C to AB is obtained by Pythagorean theorem, CD=2* radical sign 1 19.

BC=2* radical number 2 19 (Pythagorean theorem)

The distance from d to AB and AD can be obtained by the ratio of similar triangles.

The distance from d to AB is the root number 1 19.

AD is the root number 2 19.

So CD=3 root number 1 19.

Ac tension =(24/3 number of roots 1 19)*5000=(8/ number of roots1/9) * 5000.

BC tension = (root number 2 19/3 root number 1 19)*5000.
