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.
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.
No you still do the same amount of work
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!!
The woman might be drilling a hole to create a space for a fastener or anchor, such as a screw or a bolt, which will help secure two objects together. Once she finishes drilling, she will likely insert a screw, which is a type of simple machine known as an inclined plane wrapped around a cylinder. This design allows for easier application of force to hold materials together.
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.
Work
That isn't possible, not with a simple machine and not with a complicated machine, since otherwise, conservation of energy would be violated.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.

it sure did get the wok done faster!
Increase Work
If a simple machine is 100% efficient, it means that the input work done on the machine is equal to the output work produced by the machine. In other words, all the energy put into the machine is completely converted into useful work without any energy being wasted.
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
Work: The work done by the force is the same as the work done on the load in an ideal simple machine.
No you still do the same amount of 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.
