A beam AB of length 
and weight w supports a load W at its free and B and is hinged at its end A. A wire CD supports the beam at the mid point C making an angle of 300 with the horizontal. What is the value of tension T in the wire CD?
(a) $8\left ( W+\frac{w}{2} \right )$
(b) $4\left ( 2W+w \right )$
(c) $2\left ( 2W+\frac{w}{2} \right )$
(d) (c) $4\left ( W+\frac{w}{2} \right )$
