- Homework Statement
- hey, I'm wondering about the phenomenon of the experiment with a ruler and a piece of paper. Description of the experiment: we place a ruler on the edge of the table (one end of the ruler protrudes beyond the table) and then we place a piece of paper on it. When we throw the ball at the protruding end of the ruler, the ruler will not fall (it will be held by the paper). If we know the length of the ruler (protruding and not protruding), the mass of the ball and the surface of the paper, how can we calculate from what height the ball should be thrown in order for the ruler to fall or break?
- Relevant Equations
- The equations that will be needed here are certainly pressure, forces, and possibly energy, but I don't know where to start
WI know that the phenomenon occurs due to the decrease in pressure under the sheet of paper.There is therefore greater pressure above the sheet of paper, pressing down on the sheet of paper, which prevents the ruler from tearing off. However, I lack patterns and specifics
