Counterweights are objects used to balance or offset the weight of another object. They are commonly found in various applications, such as cranes, elevators, and amusement park rides. By providing an opposing force, counterweights help to stabilize systems and make them safer and more efficient. In a crane, for example, a heavy counterweight is placed on the opposite side of the load being lifted. This design allows the crane to lift heavy objects without tipping over. Similarly, in an elevator, counterweights help to balance the weight of the elevator car, making it easier to move up and down.
