A 12 m steel beam of mass 1100 kg extends 4 m beyond the edge of a flat roof. A 2,100 kg object is placed on the beam 2 m beyond the roof edge. To balance the beam an 800 kg load must be placed on the beam at what distance from the edge of the roof?

Step 1
First, we need to find the center of mass of the steel beam. Since the beam is uniform, the center of mass is at its midpoint, which is 6 meters from either end. Show more…

A 4.00-m-long, 500 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70.0 kg construction worker stands at the far end of the beam. What is the magnitude of the gravitational torque about the point where the beam is bolted into place?

A 10 m beam of mass 306 kg extends over a ledge. The beam is not attached, but simply rests on the surface. A 66 kg student intends to position the beam so that he can walk to the end of it. How far from the edge of the ledge can the beam extend?
