The truss are joined as shown in Figure P-447 to form a three-hinged arch. Determine the horizontal and vertical components of the hinge force at B and then determine the type and magnitude of force in bars BD and BE.
The center panel of the truss in Figure P-437 contains two flexible cables. What load P will cause a compressive force of 20 kN in BD? Then determine which tension diagonal BE or CD is acting and the force in it.
In Figure P-420, assume that counter diagonals act from B to E and from E to F in addition to the counter diagonals CD and DG shown in the figure. Assuming that these counter diagonals can support tension only, determine which diagonals are acting and the force in each.
