How does a simple machine such as a wheelbarrow change the way work is done?

It distributes weight upon a certain point, usually not on the user, to make moving objects easier; such as a wheelbarrow, pulley, inclined plane, etc.

How do simple machines help us?
Simple machine help us do work like lifting heavy things that we cant lift. This was done by an 8th grader at berea middle school.
Do simple machines change the amount of work being done?
No you still do the same amount of work
What is the difference between nc machining and cnc machining?
Re: Difference between CNC & NC machinesIn a Numerical Control machine, the program is fed to the machine through magnetic tapes or other such media. The original NC machines were essentially basic machine tools which were modified to have motors for movement along the axes. In a Computer Numerical Controlled machine, the machines are interfaced with computers. This makes them more versatile in the sense that, suppose a change in dimension of a part is required. In a NC machine, you would have had to change the program in the tape and then feed it to the machine again. But in a CNC machine, you just change a variable in the computer and your modification is done!!
What is Shearing mechanical process?
shearing mech. process is done by a machine known as shearing machine in which a sheet of alluminium or some other metal is cutted down in between the blade of the machine, and this process is known as shearing process.
How do you calculate temperature of a motor?
The basic equation that will enable you to determine the temperature of any electrical machine is:(W - Q) = m c (Tf - Ti)Where, W = work done on the machine, Q = heat transfer away from the machine into its surroundings, m = mass of the machine, c = specific heat capacity of the machine, and Tf and Ti the final and initial temperatures of the machine respectively.But there are so many variables involved that it would be very difficult to apply this equation in practise. For example, the ambient temperature (Ti) is variable, and you would need to know the mass and specific heat capacity for every component of the machine.So the simple answer would be to simply measure it with a thermometer!
What can be done by a simple machine?
Work
What cannot be done by a simple machine?
Increase Work
What does work input mean?
a task done by a simple machine
Is it possible to use a simple machine and do less work than you would have done without the machine?
That isn't possible, not with a simple machine and not with a complicated machine, since otherwise, conservation of energy would be violated.

How the sewing machine change the world?
it sure did get the wok done faster!
How does the output work done by machine change when friction is reduced?
Increases
What is an example of a 2nd class lever?

A fulcrum is on the left side of a board as it is moved to the right will the force be the same?
Work: The work done by the force is the same as the work done on the load in an ideal simple machine.
Do simple machines change the amount of work done?
No you still do the same amount of work
How does a simple machine make a hand brake work?
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. They can be used to increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the force.
