How does work input and work output compare?

How does work input and work output compare?

Explanation: Work output is the work done by the machine on the load while work input is the work done on the machine by effort. Input work is the work done on a machine as the input force acts through the input distance.

How does the output work compare to the input work for a machine that has an efficiency A equal to 100 %? B less than 100 %?

Machine Efficiency The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent. The closer to 100 percent a machine’s efficiency is, the better it is at reducing friction.

What is the relation between output work and input work?

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, the work output is equal to the work input i.e the efficiency is 1.

Does work output equal work input?

Work output is always less than work input, so an actual machine cannot be 100% efficient. The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.

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.

What is the comparison of work output to work input?

The output is multiplied from input. A comparison expressed as percentage of a machine work output with the work input? THE EFFICIENCY of a machine compares the output work to the input work and is expressed as a percent. What is the comparison of a machines work output with the work input?

How to calculate the efficiency of a machine?

What is the % efficiency of a machine that requires 120 J of input energy to do 35 J of useful work remember: Mechanical Efficiency is output work/input work x 100 Length of the ramp divided by the height The ideal machine advantage of a ramp (inclined plane) is equal to the Block and tackle

What is the ratio of output to input?

The ratio output/input is called efficiency which is always less than 1. The efficiency of a bicycle is typically 40%. Output is always less than input. Protecting data that matters the most. Companies plan to use confidential computing to protect their data and others moving forward. How does input and output work?

How does a machine make your job easier?

by changing the amount of force you exert, the distance over which you exert your force or the direction in which you exert your force. a machine makes work easier by multiplying either.
