What is the formula for calculating the capacity of an elevator?

The correct choice for calculating the capacity of an elevator, which is 100 lbs per square foot, is based on standards and regulations in the industry. This value reflects a common safety and design standard used to determine the maximum load an elevator can handle per square foot of its floor area.

Using this formula allows for a consistent calculation that ensures elevators are designed and evaluated effectively to accommodate typical demands while maintaining safety for all users. The industry has adopted this figure to provide a balance between adequately supporting the weight of occupants and equipment without compromising structural integrity or safety systems.

In contrast, the other values are lesser than the standard. They might not account for the typical density of people or loads that elevators regularly carry, leading to potential safety issues if such limits were to be applied in practical scenarios. Thus, adherence to the 100 lbs per square foot figure promotes reliable performance and safety compliance in elevator operations.
