Consider the plane truss with load P as shown in the figure. Let the horizontal and vertical reactions at the joint B be HB and VB, respectively and VC be the vertical reaction at the joint C.Which one of the following sets gives the correct values of VB, HB and VC?

• A. \({V_B} = 0;{H_B} = 0;{V_C} = P\)
• B. \({V_B} = \frac{P}{2};{H_B} = 0;{V_C} = \frac{P}{2}\)
• C. \({V_B} = \frac{P}{2};{H_B} = P\left( {\sin 60^\circ } \right);{V_C} = \frac{P}{2}\)
• D. \({V_B} = P;{H_B} = P\left( {\cos 60^\circ } \right);{V_C} = 0\)
