AI Thread Summary
A Year 10 student in Australia is seeking help for an Engineering Challenge that involves building an 80cm bridge using only paddle pop sticks and PVA glue, aiming to maximize weight support while minimizing mass. Suggestions for effective designs, tips, and relevant software are requested. The student considers a box-like structure based on last year's winning design and mentions researching trusses due to their structural efficiency. Discussion includes the potential application of Young's Modulus in understanding material properties. The focus remains on innovative bridge designs that can achieve the challenge's goals.

Homework Statement


Hey guys!

I am a year 10 student from Australia and our school is having an Engineering Challnege.

One of the tasks is to build a 80cm bridge using only paddle pop sticks and PVA glue. To win, the bridge must hold the most weight but have least mass.

It would be really appreciated if you could suggest any designs, tips, software for designs or anything about bridge building.

Care to give me a hand?


Homework Equations


?Maybe Young's Modulus?


The Attempt at a Solution



One of my initial ideas was to basically build a box cause last year the winnng entry was literaly like a rectanglur box
 
Physics news on Phys.org
Look up 'Trusses' - there have been hundreds designed and the properties of steel and pop sticks aren't too different at small sizes.
