Question: The triangular frame ABC can be adjusted vertically between the three equal-length cords. If it remains in a horizontal plane, determine the required distance s

The triangular frame ABC can be adjusted vertically between the three equal-length cords. If it remains in a horizontal plane, determine the required distance s so that the tension in each of the cords, OA, OB, and OC, equals F. The lamp has a mass M.
Given:
F = 20 N
M = 5 kg
g = 9.81 m/s2
d = 0.5 m
