-R Prob. 9-41

The plate shown in the figure is held in position by a cable at B, a simple support at A and a ball joint at D, considering that F1 = 733N and F2 = 224N determine the magnitude of the tension in the cable

Determine the resultant R of the Four forces acting on the simple truss. The Fourth force is acting on the node where the 25 KN is at and is directed upward with a magnitude of 15 KN. Specify the points on the x- and y-axes through which R must pass. 30° 20 kN 25 kN y 5 m 3 m 6 m 3 m ---x 30 kN
