What are the examples of microscopic systems and macroscopic

Examples of familiar macroscopic objects include systems such as the air in your room, a glass of water, a coin, and a rubber band—examples of a gas, liquid, solid, and polymer, respectively. Less familiar macroscopic systems include superconductors, cell membranes, the brain, the stock market, and neutron stars.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.
