What is the difference between equipments and machines and tools?

Equipments are physical resources serving to equip a person or thing, while machines are any device that uses energy to perform some activity and tools are devices that aid in accomplishing a task.

Tools can either be hand-held small appliances or can range from small workshop bench-mounted drills, lathes and presses up to huge industrial machine tools designed to make large pieces of raw materials - such as sheet metal, forged iron or aluminum castings - or other materials - into highly accurately machined components for manufacturing major engineered items such as vehicles, aircraft, ships, steel road and railway bridges, etc.

Machines are devices that need a person's attention when operating.

Equipment are devices that do not need this attention.

Examples: a refrigerator is equipment, a steel cutter is machine, a stove is equipment, a computer or a fax are machines; we call it anyway, "fax machine". Your car is machine/you operate it; your house, though, is "equipped with A/C and fan" because you do not pay attention to them when operating. The water heater is equipment. The pressure washer is machine, the air-compressor is equipment.
