The correct answer is 'chain fall'.
Explicación
## Step 1The problem is asking us to identify which of the given devices has a control that allows for the free-fall of a load. The options provided are: fork in, chain fall, chain hoist, and come-along.## Step 2A chain fall, also known as a gravity lift, is a type of lifting device that uses a chain and a sprocket to lift or lower a load. It has a control mechanism that allows the load to be released, leading to a free-fall situation.## Step 3On the other hand, a fork in, chain hoist, and come-along do not have a control that allows for the free-fall of a load. A fork in is a type of lifting device that uses a forked metal prong to lift and carry loads. A chain hoist is a type of lifting device that uses a chain and a pulley to lift and lower loads. A come-along is a type of hand-operated winch used to pull or lift heavy loads.
