Question

For a 2-meter beam that weighs 24 kg, where is the center of mass located?

A. At the midpoint of the beam
B. Closer to the heavier end
C. Closer to the lighter end
D. Impossible to determine

Answer 1

For a beam with uniform density, the center of mass is at the geometric center; thus, for a 2-meter, 24 kg beam, it is at the midpoint.

Step-by-step explanation:

The location of the center of mass of an object is determined by the distribution of the mass within the object. For objects with uniform density and uniform shape, such as a beam with constant thickness and material throughout its length, the center of mass is located at the geometric center. Therefore, for a 2-meter beam that weighs 24 kg, assuming that the beam has a uniform density and no additional weight information is given, the center of mass is located at the midpoint of the beam.
