7. The pull tab was a major advance in the engineering design of beverage containers. The tab pivots on a central bolt in the can’s top. When you pull upward on one end of the tab, the other end presses downward on a portion of the can’s top that has been scored. If you pull upward with a 10 force on the part of the tab that is 1.8 cm away from where the tab is pivoted, what force magnitude acts on the scored section that is 0.73 cm from the pivot?
