How we draw the freebody Diagram for B ( and how we relove it with angle 60 dgree ) ???

Extracted text: Figure Q1(a) shows a bracket that has a load of 1.6 kN applied at one end as shown in the figure. The bracket is supported by a pin at the end A and by a roller which rests on a rigid surface near pin B as illustrated in the figure. i) Draw the free body diagram for the bracket together with the roller. ii) Calculate the reaction of the support on the roller i) Calculate the magnitude and direction of the reaction at the pin A -120 mm- B. 30° -180 mm 1.6 kN Figure Q1(a)
