As the human operator is a central part of a human-machine system, the correction of these problems is necessary for the operation of safe and efficient systems.
An operating budget may include estimates of the expected workload for a specific activity.
Horses are, obviously, not perfect machines and over short time periods are capable of as much as 14 hp, and over long periods of exertion output an average of less than 1 hp.
