Example 4.2 The uniform, horizontal beam shown in Fig. 4.14 is hinged to the ground at point A. A frictionless roller is placed between the beam and the ceiling at point D to constrain the counterclockwise rotation of the beam about the hinge joint. A force that makes an angle ß = 60° with the horizontal is applied at point B. The magnitude of the applied force is P = 1,000 N. Point C represents the center of gravity of the beam. The distance between points A and B is l= 4m and the distance between points A and D is d = 3 m. The beam weighs W = 800 N. Calculate the reactions on the beam at points A and D. %3D A C D B d

An 8-m long cantilever beam is loaded with vertical forces A = 60 kN and B = 108 kN, separated by a distance d = 5.6 m, as shown. Replace the two forces with a single equivalent force R and determine the distance x-bar (x¯) from the left end of the beam to the line of action of R.
A uniform horizontal strut weighs 425 N. One end of the strut is attached to a hinged support at the wall, and the other end of the strut is attached to a sign that weighs 235 N. The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the strut, find the tension in the cable and the force at the hinge of the strut.
