Question

Adam has created a triangular table, as shown. Because his table will have only one pedestal leg, he needs to find the balance point of the table top. To do this, he has located the centroid of the table top, as shown on the right. However, he is not sure if that point really is the center of mass. How can you prove to Adam that this point really is the center of mass?

Answer 1

It is important to know that the centroid of a triangle refers to its center of mass.

A centroid is a point formed by the intersection of the three medians of the triangle, knowing that a median is a segment that goes from a vertex to the opposite divide dividing it in two equal parts.

Hence, the correct option is the last one because each median is a balanced line.
