Question
Please solve it properly thanks.
In this experiment you will test the stability of a stack of block: as the angle of the surface the stack rests on gradually increases. Using a fishing sinker tied to the center of mass, you will be able to see the position of the center of mass relative to the base of the object as it begins to tip ever. 1 Fishing Sinker Protractor 30 cm. String Masking Tape Ramp Runway Ruler 4 Wooden Blocks *1 Empty Water Bottle with Lid *Water *You Must Provide 1. Mark the location of the center of gravity on one side of a wooden block with a piece of masking tape (the middle). 2. Using masking tape, attach one block above and below your original so that your center of gravity mark is visible, making a 3-block-high tower. 3. Use a ruler to measure and cut 30 cm. of string. Tape the string to the mark on the middle block with 20 cm hanging downward. 4. Attach a sinker to the end of the string. Set the block stack on top of the ramp, and line the edge of the ramp runway up with the edge of a table so that the string can dangle. 5. Increase the incline of the ramp runway, and notice the relationship between when the block stack starts to tip over and the location of the string. Record your observations in Table 1. 6. Try this out with four blocks stacked. Make sure to move your center of mass to the middle of the to tower (between the second and third blocks). Record your observations in Table 1. 1. Fill one of the water bottle one fourth full of water. 2. Stand the bottle upright on a table. Slowly tilt the bottle by pushing the top of one side with one hand while supporting the opposite side of the bottle with a finger form your other hand. 3. Push the top of the battle further and further checking every once in a while to see if the battle will fall back upright if you were to stop pushing. 4. Continue pushing the top of the bottle up until an angle where the bottle will not tip back upright and support that angle with the finger form your other hand. 5. Use the protractor to measure the angle between the side of the bottle your finger is supporting and the table. Record the angle in Table 2. 6. Repeat Steps 2 - 5 with the bottle half full, three fourths full and completely full. Record your angles in Table 2. 1. When did the blocks typically fall over? 2. Which stack of blocks (3 or 4) had a lower center of mass? Which set tipped over at the largest angle? How do you know? 3. if you were building a skyscraper in a windy city, where would you want most of the building's weight to be located? 4. Draw a rough diagram for each case showing the placement of the center of mass (point CM) and the maximum angle of the bottle reached. 5. Explain why you were able to tilt the bottle more in some cases more than others. 6. How soon do you think the bottle would tip over if you could fill only the top half?Explanation / Answer
This is totally practical based question.I can't help you with values but I can help you with concept of toppling that is required here ....
Toppling is a phenomenon that generally happens when force is applied on a body of smaller base area.
Suppose we have a block as shown in the figure, when we apply force there should be translational motion. But sometimes instead of translational motion the body rotates about an axis passing through the rightmost edge.
Suppose the force is applied on the body as shown below, In order to counter the torque caused by F about center of mass the normal will shift. [Toppling] We have to find the maximum force that can be applied so that the block does not topple, in that case the normal will pass through the extreme right corner ,block will topple..
