Center of Mass
Belinda needs tofind the center of mass of a sculpture she hasmade so that it will hang in a gallery correctly. The sculpture isall in one plane and consists of various shaped uniform objectswith masses and sizes as shown. The length of the rectangle is L= 1.6 m and the mass of the octagon is M = 2 kg. Where is thecenter of mass of this sculpture? Assume the thin rods connectingthe larger pieces have no mass and place the...

Vehicles with a center of mass that is high above the ground are more likely to "rollover" in an accident or even when turning quickly at high speed. (Rollover accidents are also more likely to result in fatalities.) A person decides to transport a load of bricks on the top of his van. The mass of the van is 1,044 kg, and without the bricks, the height of the van's...

Problem 4.11 A uniform slender rod of mass m, mass center G and length 21 is set against a vertical wall, with its lower extremity co- inciding with the corner O of the horizon tal support. A small perturbation destroys this unstable equilibrium, and the rod rotates about O. The contact is assumed frictionless. The inclination of the rod with the vertical is described by angle θ. a. Show that the motion of the rod is a rota tion about...

AXis Two spheres of mass m are attached to a light rod of length 2L. The rod is fixed at its center to a freely-rotating axis. The rod is horizontal when a small bird of mass 5m carefully lands on the right sphere.
