what is the earliest recorded uses of somple machines
it is some thing that we use every day
A machine that uses two or more simple machines is called a compound machine. Compound machines combine the mechanical advantages of simple machines, such as levers, pulleys, and gears, to perform complex tasks more efficiently. Examples include bicycles, which utilize gears and levers, and cranes, which incorporate pulleys and levers. These machines enhance the overall effectiveness of mechanical work.
a bicycle
they uses their brains for that matter.
When a human uses a complex machine it helps him or her.
a knife uses a very thin wedge to split whatever the object is
Some common questions about simple machines include: How do simple machines make work easier? What are the different types of simple machines? How do simple machines affect force and distance in work? How can simple machines be combined to create complex machines?
A rowboat is a compound machine because it uses a combination of simple machines, such as levers for the oars and pulleys for the anchor system.
A CATAPULT IS A LEVER!!!
6 simple machines.
Simple machines found at home include a lever (like a seesaw), a pulley (used in curtains), and an inclined plane (ramp for loading). Complex machines include a washing machine, which uses a combination of levers and pulleys, a dishwasher that incorporates multiple simple machines, and a microwave, which combines electrical and mechanical components to heat food. Other examples of complex machines are a blender, vacuum cleaner, and refrigerator. Each of these machines utilizes various simple machines to perform specific tasks efficiently.
