Consider the beams below. They are balanced as shown on a fulcrum. For which of the beams is the center of mass not located above the fulcrum?
Homework Answers
As the beams are balanced over fulcrum, that means mass in equal both side for both the beams. Both the beams have same centre of mass located on the fulcrum. If it was not located over the fulcrum then there would be a torque acting in the direction of large amount of the mass.

1. A lever is a rigid stick balanced across a fulcrum F, as shown in Figure 1. Mass m hangs a distance L from the fulcrum, and mass m' hangs a distance I/ from the fulcrum. Suppose for the sake of argument that the mass of the lever itself is negligible. In equilibrium the masses arranged in this way will balance each other, and the lever is motionless. To achieve this, the lever must exert a set of complicated forces...

Problem 1 Beams (a) - (g) shown below are simply supported and loaded at their ends by two concentrated moments of magnitude PL/10. In addition to the moments, beams (a) – (d) are subject to a uniformly distributed load of magnitude 2P/L, and beams (e) – (h) are subject to a concentrated load at midspan of magnitude P (note the directions of the loads). All beams have length L. Draw the shear and moment diagram for all cases shown. (b)....
