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.
you will have something like metal, toolsand the stuff to build the swings and things like that
A compound machine.
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.
