MecMovies 4.0 : M4.3: Load Capacity of Beam-strut Structure

scene 3 of 8

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.

In terms of $w$ , the resultant force acting on pin $C$ can be expressed as:

$|C| = \sqrt{{(C_{x})}^{2} + {(C_{y})}^{2}} = (2.9554 m) (w kN/ m)$
