The purpose of a simple machine is to facilitate or make whatever job you are doing easier. For Ex. A stapler uses a lever. Which is easier forcing a staple with your fingers or just pushing a piece of plastic.
A complex machine.
A train is not a simple machine.
A fulcrum is a part of a simple machine, the lever. Without the fulcrum what is left of the simple machine can no longer increase the applied force and is no longer a simple machine.
yes a door knod is a simple machine
A spade is a simple mechanical (tool) machine.
A knife is classified as a simple machine because it has only one function or movement, which is to cut or slice through objects. It utilizes a straight blade for this purpose, making it an example of a simple machine known as a wedge.
to make your work easier . to less the working time
The function of the simple pulley machine is the transfer the amount of force by utilizing a cable of sorts to lift while the other side is pulled. Simply put, when on side is pulled down, the other side is lifted.
The screw is a simple machine that depends on friction to function properly. When a screw is turned, the threads create friction with the material it is being inserted into, allowing it to hold objects together or lift loads.
Yes, a comb is considered a simple machine because it has a basic mechanical function of separating or straightening hair by utilizing the concept of wedges and levers.
An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
compound machine
A geometric compass is considered a simple machine because it only has one main moving part that enables it to perform its function of drawing circles and arcs.
for me, the spoon is a simple machine. because it is use to eat. a spoon is useful to eat.. only that if it is a compound machines it can use as many.. in compound machines it can be use as many things...
A knife is not considered a simple machine because its primary function is to cut or slice by applying force to a sharp edge, rather than transferring or transforming mechanical energy as simple machines do. It does not have any moving parts or internal mechanisms that provide mechanical advantage.
A pendulum contraption is typically classified as a compound machine, as it combines multiple simple machines like a lever, a wheel and axle, and potentially a pulley system to function.
A pulley isn't a kind of simple machine, it is a simple machine
