One end of a horizontal uniform beam of weight W and length L is hinged on a vertical wall at point O and its other end is supported by a light inextensible rope. The other end of the rope is fixed at point Q, at a height L above the hinged at point O. A block of weight (alpha)W is attached at point P of the beam, as shown in the figure (not to scale). The rope can sustain a maximum tension of [2(2)^(1/2)]W. Which of the following statement(s) is (are) correct?
A) The vertical component of the reaction force at O does not depend on (alpha).
B) The horizontal component of the reaction force at O is equal to W for alpha=0.5.
C) The tension in the rope is 2W for alpha=0.5.
D) The rope breaks if alpha (is greater than) 1.5.
