The plane pin-jointed truss ABCD shown in Figure MKC1 is loaded with a downward concentrated point load of 150 kN at B. Determine the reactions and the internal forces and consider the following statements. 150kN B 4 D 4 C 3 1. The vertical reactions at A and C are at a ratio Va: Vc = 2:1 2. Element BD carries no internal force. 3. The magnitude of the internal force carried in element CD is 125 kN. 4. The magnitude of the internal force carried in element BC is 125 kN. 5. Internal force in element AB is compressive. Which of the above statements are true? 1, 3 and 4 only 2, 4 and 5 only 2, 3 and 5 only All of them None of them The plane pin-jointed truss ABCD shown in Figure MKC1 is loaded with a downward concentrated point load of 150 kN at B.
