If spring BC is unstretched with θ = 0° and the bell crank achieves its equilibrium position when θ = 15°, determine the force F applied perpendicular to segment AD and the horizontal and vertical components of reaction at pin A. Spring BC remains in the horizontal postion at all times due to the roller at C.
