Question

1) See Figure 1. A uniform beam with a mass of 450 kg spans the distance of 7.0 m between the piers of a small bridge. Two objects sit on the beam. The first object has a weight of 3400 N and is located 2.0 meters from one end of the beam, while the second object has a weight of 1200 N and is located 1.0 meter from the opposite end of the beam. a) Sketch a free body diagram of the beam, showing all the forces acting on the beam and the points at which these force act. Be sure to label the center of gravity of the beam. b) Identify the forces acting on the beam. Upward 1) 2) Downward 3) 4) 5)
