pulley and two other ones that i dont know
compound machine
A machine is classified as a compound machine when it consists of two or more simple machines working together to perform a task. Simple machines include levers, pulleys, inclined planes, wheels and axles, screws, and wedges. Compound machines utilize the mechanical advantages of these simple machines to increase efficiency and reduce the amount of force needed to accomplish work. Examples include a bicycle, which combines wheels, levers, and pulleys.
A pizza cutter primarily incorporates two simple machines: the wheel and axle, and the lever. The circular blade acts as the wheel, rotating on the axle to slice through the pizza. Additionally, the handle of some pizza cutters can function as a lever, providing leverage to apply pressure and maneuver the cutter effectively. Together, these simple machines enhance the efficiency of cutting pizza.
A hole punch primarily consists of two simple machines: the lever and the wedge. The lever is the mechanism that allows the user to apply force to the punch, making it easier to create holes in paper. The wedge is formed by the sharp tip of the punch, which penetrates the material, separating it to create a hole. Together, these machines work to efficiently perforate sheets of paper.

The two reasons why people use simple machines are because they make things easier to pull and lift.

simple machines are put together by connecting. for example, in cars. simple machines work together by putting their strength

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.

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