Simple machines are any device used to change the direction and or magnitude of a force. Levers, pulleys, wheels, and the inclined plane are all examples of simple machines.
A straw is not a simple machine. Simple machines are mechanical devices that change the direction of a force. A straw does not redirect the direction of the force.
Simple machine helps us to increase the power and force for change.
Simple machines usually decrease the amount of force needed and therefore making work easier. In some cases speed is traded like a baseball bat. It is called a third class lever. A simple pulley doesn't change the force but does change the direction.
Simple machines help people lift and pull heavy objects. Simple machines like pulleys have been around for decades helping people work more efficiently.
Increasing force. Reduction in force. Power transmission. Force for change.

Simple machines lets you trade force for distance, or the other way around. Or they change the direction of a force.

Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.

No, a shelf support is likely a cantilevered beam, that is not a simple machine. Simple machines exploit leverage to increase or change the direction of force, a cantilevered beam merely supports a force.

force
Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.
