SUMMARY

The discussion focuses on constructing a model that maximizes fall time along a 3-meter runner using materials like paper, foil, and tights. Participants suggest using a paper towel parachute with air circulation holes to enhance stability and a propeller model with three blades for increased air resistance. The goal is to effectively utilize air resistance to prolong the descent time of the model while adhering to specific design constraints, including a hole for attachment to the runner.

PREREQUISITES
  • Understanding of basic aerodynamics principles
  • Familiarity with materials like paper and foil for model construction
  • Knowledge of air resistance and its effects on falling objects
  • Experience with simple mechanical designs, such as propellers
NEXT STEPS
  • Research the principles of air resistance and drag in aerodynamics
  • Explore design techniques for creating effective parachutes
  • Investigate the mechanics of propeller design and its impact on flight
  • Experiment with different materials to optimize model performance
USEFUL FOR

This discussion is beneficial for students, educators, and hobbyists interested in physics, engineering, and model design, particularly those focused on aerodynamics and maximizing fall time in experimental setups.

Homework Statement



The problem is to construct a model out of ordinary materials such as paper, blotting paper, foil, tights and so on, that is supposed to fall along about 3 metre long runner with as longest time as possible. (with the inspirations like maple seed)

The Attempt at a Solution



I was thinking about a paper towel parachute with holes in it that would keep the air circulation not to swing around... Or the propeller model with tube (has to have a hole for attaching it to the runner) and 3 blades like in helicopter...

What is the best way to use air resistance in this case?
I'm sorry for such dumb questions =_=,
thank you
 
Physics news on Phys.org
"to fall along about 3 metre long runner with as longest time as possible."

Please elaborate...
 
There is a line attached to a celling and there should be a hole in the model so that it goes along a restricted space (to measure time equally)
