That isn't possible, not with a simple machine and not with a complicated machine, since otherwise, conservation of energy would be violated.
what? how in any possible way could a suitcase be a machine? the only thing it does is open and close. i would have thought something like this would not need asking.
A paddle brush is NOT a simple machine, a simple machine is defined as: a machine or complex tool that eases the load by changing either the magnitude of the direction of a force to match the force to the capability of the machine or the person. So, the force used is from the PERSON not the TOOL without the human force, no work, or power would result.
An ideal machine that experiences no friction is known as a frictionless machine. However, in reality, achieving a completely frictionless machine is not possible due to factors such as surface roughness, molecular forces, and energy losses.
When the output force is greater than the input force on a simple machine, the machine provides a mechanical advantage, making it easier to perform work. This allows the machine to lift or move heavier loads than would be possible with just the input force alone.
no
a wedge
In theory, if you could put the proper nutrients into it, it would be possible to invent that machine.
No. Gears are a type of simple machine. Combined with another simple machine, it would then make a compound machine.
A screw is the simple machine which holds two boards together. In this case it is not acting as a machine though.
a complex machine would be a car, but a simple machine would be a wheel and axle. an example of a wheel and axle would be a steering wheel
That would be a lever.
That would be a lever.
