Final answer:
When attaching a hoist to a structure, make sure the structure is strong enough and take into account the change in the value of g when designing support for tall buildings.
Step-by-step explanation:
When attaching a hoist to a structure, it is important to ensure that the structure is strong enough to support the weight being lifted. This is especially crucial for tall buildings, where the weight at the top can differ from the weight on the first floor. Engineers designing structural support for very tall buildings need to take into account the change in the value of g, the acceleration due to gravity, as it can affect the load and stress on the structure.
