# Diagram Abcd Rigid Stationary Beam 450 M Long Weight 0450 Kn C Centre Gravity Centre Mass Q17791354

In the diagram ABCD is a rigid stationary beam 4.50 m long of weight 0.450 kN, C is the centre of gravity (centre of mass) of the beam and AC = 2.10 m. The tension in the cable BE, which is at right angles to the beam, is 2.25 kN. (a) Draw a free body diagram to show the forces that act on the beam. Show the force at A as vertical and horizontal components. (b) Determine the weight of the load L. (c) Find the vertical and horizontal components of the force which the pin joint at A applies to the beam.Show transcribed image text In the diagram ABCD is a rigid stationary beam 4.50 m long of weight 0.450 kN, C is the centre of gravity (centre of mass) of the beam and AC = 2.10 m.
