Calculate the work input in a pulley by using the previous readings in the correct mathematical equation: Work (W) equals force (f) multiplied by distance (d), or W=fd . The work done by the pulley is the equation of weight (w) multiplied by height traveled (h).
How do you calculate efficiency and input work?
The work efficiency formula is efficiency = output / input , and you can multiply the result by 100 to get work efficiency as a percentage.
What does work input mean?
Work input is work done on a machine to get the desired output . Work output is the amount of desired work that is done by a machine. For an ideal machine
How do you calculate pulley work?
Work is defined as motion in the direction of a force. Work is done to pull the pulleys upward, as a student s hand creates an upward force that lifts the weight. This can be quantified in the formula: Work = Force x Distance (W= Fd) .
How do you calculate work?
The formula for work is , work equals force times distance . In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity.
What is input work example?
Input work is the work done on a machine as the input force acts through the input distance . Other ways it would be the work done on a body or system, that is, forces that are applied to the body or system. ... The machine does to the object to increase the output distance.
How does an input work?
Input: Getting Data from the User to the Computer . Some input data can go directly to the computer for processing. Input in this category includes bar codes, speech that enters the computer through a microphone, and data entered by means of a device that converts motions to on-screen action.
What’s the formula for efficiency?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C , where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is the formula for work output?
The formula calculating work output is F*D/T , where F is the force exerted, D is the distance and T is the time. The work output of a system is also described as its Power. In order for work to be done, force has to be applied in the direction of the motion.
What is the formula for power output?
Power = force multiplied by speed (velocity) P = F × v.
What are two examples of a pulley?
- Elevators use multiple pulleys in order to function.
- A cargo lift system that allows for items to be hoisted to higher floors is a pulley system.
- Wells use the pulley system to hoist the bucket out of the well.
- Many types of exercise equipment use pulleys in order to function.
What is the formula for simple machines?
| ideal mechanical advantage (general) IMA=FrFe=dedr | input work Wi=Fidi | output work Wo=Fodo | efficiency output % efficiency=WoWi×100 |

How much force is needed to lift the weight pulley?
One wheel. If you have a single wheel and a rope, a pulley helps you reverse the direction of your lifting force. So, as in the picture below, you pull the rope down to lift the weight up. If you want to lift something that weighs 100kg, you have to pull down with a force equivalent to 100kg , which is 1000N (newtons).
What is work output work input?
• Work In, Work Out: The work that you do on a machine is called work input. The work done by the machine on an object is called work output.
What is the difference between input force and work input?
Input force is the force that you exert on an object. Output force is the force the machine exerts on an object. ... Input work is the input force times (x) the input distance . Output work is the output force times (x) the output distance.
Does work output equal work input?
Solution: Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine. For an ideal machine
