How is the work output of a machine related to its work input?

Simple Machines | Questions with Short/Long Answers Work input refers to the work done on a machine to produce the intended result. The quantity of intended work performed by a machine is referred to as work output. The work output of an ideal machine is equal to the work input, i.e., the efficiency equals one. In real machines, the work output generally is less than the work input.

For example, let's say you want to know how much water your washing machine can pump out in one minute. The work output of your washing machine is the amount of water it pumps out in one minute, and the work input is the number of minutes you put in the machine per load. Work output is the number of gallons of water pumped out by the machine in one minute divided by the number of minutes you put in the machine per load. Work output is the amount of water your washing machine can pump out in one minute.

In general, the work output of a machine is less than the work input. This is because some of the energy input into the machine is lost in friction or not used to perform work. For example, if you push a car for a mile at 10 miles per hour, it will consume 100 watts of power. However, only 90 watts of that power is transferred from the engine to the wheels, while the other 10 watts is lost due to friction between the car body and the road.

What is the work input for a machine?

Work input refers to the work done on a machine to produce the intended result. In practice, however, no machine is completely efficient; some energy is lost in conversion processes. Thus, a machine will always have a degree of efficiency which is less than 100%.

For example, a mill that can process 500 pounds of corn and produce a coarse meal outputting 50 pounds of fine meal has an efficiency of 25%. That is, it uses four times as much energy to make the fine meal as it does to make the coarse meal.

The work input of a mill is the weight of the corn divided by its efficiency. That is, the work input in this case is 500 divided by 25, or 20 pounds per ton of corn.

Some machines have many parts that move at high speeds, such as motors and turbines. These parts use energy when they are moving and require maintenance like any other mechanical device. Other machines have large amounts of force available from their engines or electric motors, such as drills and mixers. They do not need maintenance like those with moving parts. All tools wear out over time and must be replaced.

What is the input and output of a machine?

Question 7: Work input refers to the work done on a machine to produce the desired result. The amount of unwanted or ineffective work performed by a machine is its waste product.

The input of a machine is everything that causes the machine to perform its function effectively. For example, the input of a drill is its battery; without a battery, the drill will not be able to break down rock. The output of a drill is the hole it breaks out of the rock; this is the only use for which the drill was designed, so it is effective performance. The input of a hammer is its head; without a head, it is just a stick. The output of a hammer is whatever you want it to break off your stick, such as nails or rocks.

Waste products are the output of a machine that does not help the operator achieve his or her goal. For example, if a drill's sole purpose is to make holes in rock, then the waste product of that drill is dust. Dust is waste product because it is not useful for further drilling or pounding nails.

Output can also be called product. So, the output of a drill is its product—holes in rock.
