The tab is a simple machine. What is the mechanical advantage of the tab? a 20.0 b 10.0 c 0.3 d 3.0
The mechanical advantage of a simple machine is defined as the ratio of the output force to the input force. In the case of the tab, the output force is the force exerted by the tab itself, and the input force is the force applied to the tab.
If the tab provides a mechanical advantage greater than 1, it means that the output force is greater than the input force, making the tab a type of lever.
If the tab provides a mechanical advantage less than 1, it means that the output force is less than the input force, making the tab a type of mechanical disadvantage.
Since the mechanical advantage cannot be negative, the correct answer is: d) 3.0
