A lever. The concept of leverage involves using a bar or beam (job) to multiply or change the direction of a force applied to an object in order to make work easier.
A simple machine.
The force applied to a simple machine is called effort/input force.
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.
A wedge is a simple machine. A bike is not considered a simple machine because it is composed of many complex systems working together to enable motion.
The mechanical advantage of a compound machine is the multiple of the separate mechanical advantages of each simple machine. The efficiency of the compound machine is also the multiple of the separate efficiencies of each simple machine. So the work in to the first machine multiplied by all of the simple machine efficiencies gives you the work out of the last machine
wedge is another simple machine kind of lever
it is not the same as sink
An Inclined Plane
Lever Pulley Gear Inclined planes wheels ; and axles
I think screws but there's probably more. Try googleing it.(that's what i did)
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.
The different kinds of simple machines are: 1. Lever (and fulcrum sometimes) 2. Inclined Plane 3. Pulley 4. Screw 5. Wedge 6. Wheel and Axle 7. And Gears
Because it makes our job much much more easyier
A pulley isn't a kind of simple machine, it is a simple machine
simple machine
Its a simple machine which can crush any complex machine
i think that it very much depends on opinion , but basically it is. it has a hinge and makes a job easier so it is a machine , i guess.
