Best Egg Drop Contest Shock Absorber?

AI Thread Summary
The discussion focuses on a grade 7 student's egg drop project utilizing shock-absorbent materials like cardboard, styrofoam, and sponges. The student seeks assistance in understanding the physics of shock absorbency and creating a free body diagram. Participants encourage the student to explore existing designs and research shock-absorbing devices for inspiration. Additionally, they inquire about the specific rules of the contest to provide more tailored advice. Overall, the thread emphasizes the importance of research and understanding the underlying physics for successful project design.

TL;DR Summary: egg drop report

i have an egg drop report, and my contraption is based off of shock absorbant materials (cardboard, styrofoam, and sponges). idk how to draw a free body diagram about this, or the physics behind shock absorbency. can someone help me please? (grade7)

Welcome to PF. :smile:

What reading have you done so far on this project? What shock absorbing devices have you found in a Google Images search for such contests? Do they give you some ideas?

What are the contest rules?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
