Looking at the Stirling Engine may be a good place to start. See the link below.
It is lower because compound machines have more moving parts that a simple machine does.
The transmission lever is very simple and there is no friction.
They have to overcome less friction
High-efficiency machines do more for less and are therefore more desirable than a low-efficiency machine.AnswerHigher efficiency means lower energy losses and, therefore, such machines are more economical than low-efficiency machines.
A CATAPULT IS A LEVER!!!
6 simple machines.
Simple Machines was created in 1990.
Simple Machines ended in 1998.
The similarities are that simple and complex machines are both made up of simple machines
well no there is not, simple machines are machines that are like that same machine ex. a roller coaster and a bath tub are simple machines
Many things we do during the day with simple machines. We cut with scissors. Doors will open soda. Simple Machines is extremely important role in engineering. Simple machines can not work without sophisticated machines.
Simple machines can be used to transport things.
