compound machine
The similarities are that simple and complex machines are both made up of simple machines
Complex machines are made out of multiple simple machines like axels, levers and pulleys make up a catapult on wheels.

Compound machines are things that are made up of 1 or more simple machines. A screw isn't made up of any simple machines unless you count the screw as a simple machine.
No. It's a compound machine made of two simple machines: lever and wheel & axle.
The two types of mechanical devices are simple machines and complex machines. Simple machines include tools like levers, pulleys, and screws, while complex machines are made up of multiple simple machines working together, such as engines or robots.

No, not all machines require the use of simple machines. Some machines rely on more complex mechanisms or technologies to function efficiently. Simple machines are often used to make work easier by multiplying or redirecting force, but they are not a requirement for all machines.
They are called compound machines. :)Hope that helps
screws have something called a thread, and this thread wraps around the screw. You can call the thread a kind of ramp, because this thread prevents the screw from falling off.
