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.
When two or more simple machines work together, they are called a compound machine. Compound machines are combinations of simple machines that work together to make tasks easier or more efficient. Examples include bicycles, wheelbarrows, and can openers.
pulley and two other ones that i dont know

Complex machines are made out of multiple simple machines like axels, levers and pulleys make up a catapult on wheels.
