Editing Workload (section)

==Quantified effort==
Workload can also refer to the total energy output of a system, particularly of a person or animal performing a strenuous task over time. One particular application of this is [[powerlifting|weight lifting]]/[[weights training]], where both anecdotal evidence and scientific research have shown that it is the total "workload" that is important to muscle growth, as opposed to just the load, just the volume, or "time under tension". In these and related uses, "workload" can be broken up into "work+load", referring to the work done with a given load. In terms of weights training, the "load" refers to the heaviness of the weight being lifted (20&nbsp;kg is a more significant load than 10&nbsp;kg), and "work" refers to the volume, or the total number of [[wots this?|rep]]s and sets done with that weight (20 reps are more work than ten reps, but two sets of 10 reps are the same work as 1 set of 20 reps, its just that the human body cannot do 20reps of heavy weight without a rest, so its best to think of 2x10 as being 20 reps, with a rest in the middle).

This theory was also used to determine [[horse power]] (hp), which was defined as the amount of work a horse could do with a given load over time. The wheel that the horse turned in Watt's original experiment put a specific load on the horse's muscles, and the horse could do a certain amount of work with this load in a minute. Provided the horse was a perfect machine, it would be capable of a constant maximum workload. Increasing the load by a given percentage would decrease the possible work done by the same percentage so that it would still equal "1 hp". Horses are not perfect machines and, over short periods, are capable of as much as 14&nbsp;hp, and over long periods of exertion, output an average of less than 1&nbsp;hp.

The theory can also be applied to [[automobiles]] or other machines, which are slightly more "perfect" than animals. Making a car heavier, for instance, increases the load that the engine must pull. Likewise, making it more aerodynamic decreases drag, which also acts as a load on the car. Torque can be considered the ability to move a load, and the revs are how much work it can do with that load in a given amount of time. Therefore, torque and revs together create kilowatts or total power output. Total output can be related to the "workload" of the engine/car or how much work it can do with a given load. As engines are more mechanically perfect than animals' muscles and do not fatigue similarly, they will conform much more closely to the formula that if you apply more load, they will do less work, and vice versa.
