The figure shows the free body diagram of the beam. The reaction forces at C are C subscript x and C subscript y directed horizontally to the right and vertically upwards respectively. The load on the beam is 3.6 meters times w kilo newton per meter and it acts at a distance of 1.8 meters from C. The force along the support rod directed away from the point B is F subscript 1 at an angle of 35 degrees with the horizontal.

Substitute this result into the other equations so that Cx and Cy are also expressed in terms of w:

MC=-(3.6 m)(w kN/m)(1.8 m)-(5.0 m)F1sin(35.0)=0

F1=-(2.2595 m)(w kN/m)


Fx=Cx-F1cos(35.0)=0

Cx=-(1.8509 m)(w kN/m)


Fy=Cy-(3.6 m)(w kN/m)-F1sin(35.0)=0

Cy=(2.3040 m)(w kN/m)
