Weight capacity refers to the maximum amount of weight that an object, structure, or vehicle can safely support or carry. This measurement is crucial for ensuring safety and preventing damage. For example, the weight capacity of a bridge indicates how much load it can handle without risking structural failure. Different items have different weight capacities based on their design and materials. For instance, a chair may have a weight capacity of 250 pounds, while a truck can carry several tons. Knowing the weight capacity helps users make informed decisions and avoid overloading, which can lead to accidents or damage.
