A cable and a spring are connected together at point B and held in equilibrium by a vertical force F, as shown in the figure below. The cable has a length LAB = 1 ft and is oriented at an angle = 30° from the horizontal, and the spring has a spring constant k = 25 lb/ft. Note that the cable and unstretched spring were initially aligned horizontally between points A and C before loading, with a combined length of Lw= 2 ft. Determine the force in the spring (FBC) and the applied force F. W

Transcribed Image Text:A cable and a spring are connected together at point B and held in equilibrium by a vertical force F, as shown
in the figure below. The cable has a length LAB = 1 ft and is oriented at an angle 0 = 30° from the
horizontal, and the spring has a spring constant k = 25 lb/ft. Note that the cable and unstretched spring
were initially aligned horizontally between points A and C before loading, with a combined length of
Lw=2 ft. Determine the force in the spring (FBC) and the applied force F.
