Design
Useful 41 Pcs (Including Box) Home Tool Kitis truly a savior. But what defines a tool or machine? The simplest tools, such as the lever, offer us a mechanical advantage. Simple tools multiply the force we exert on a tool at the cost of increasing the distance we need to sustain the force. This trade-off occurs because simple tools (ideally) do not alter the amount of work done. Work is the product of distance and force, so by increasing the distance via a tool one can decrease the force required. The ratio between the force exerted by the tool and the force applied to the tool defines the mechanical advantage.
