Counterweighted is an adjective used to describe an item that has a weight opposite to the main object. This helps it to remain stable and avoid tipping over. Some synonyms for counterweighted include balanced, stabilized, and equalized. Additionally, it could be described as having a counterpoise, which means a balancing weight that helps to offset the weight of the object. Other synonyms include offset, counterbalance, and equilibrium. With these synonyms, it is clear that the word counterweighted is often used in mechanical and engineering contexts, but any item that needs to remain stable can be described with one of these terms.
