What is a machine?
A machine is a device consisting of fixed and moving parts that modifies energy and transmits it in a more useful form.
Any mechanical or electrical device that automatically performs tasks or assists in performing tasks is a machine.
What should you know about machines?
Do not elaborate on machines as simple machines and compound machines.
Simple machines that some people elaborate are devices.
Machines or compound machines are combinations of devices.
Why do we use machines?
We use machines to reduce the amount of effort or work we exert, and also to increase our ability to lift or move objects.
What devices are useful in making machines?
Incline plane
Lever
Pulley
Screw
Wheel
Wedge
Some people call these devices simple machines.
Calling them devices instead of machines is a better option.
All the machines are made up of elements or parts and units.
Each element in turn can be a complete part or made up of several small pieces that are joined together by riveting, welding, etc.
What are recommendations to other experienced engineers?
Do not include incline plane, lever, pulley, screw, wheel, or wedge as machines. Include them in devices.
What are the types of machines?
How are machines classified?
Machines that generate mechanical energy
Machines that transform mechanical energy
Machines that utilize mechanical energy
