SUMMARY

The discussion focuses on constructing a popsicle stick tower capable of supporting at least 100 lbs, with specific dimensions of 15 cm in width and height. The design proposed includes a square base with a four-cornered skeleton and triangular formations on the sides to enhance structural integrity. Strong glue joints are emphasized as critical for durability, and using additional sticks to reinforce joints is recommended for increased strength. The requirement for a hollow center, accommodating a 2-inch diameter pipe, is also noted as a key design consideration.

PREREQUISITES
  • Understanding of basic structural engineering principles
  • Knowledge of material properties, specifically the strength of popsicle sticks
  • Experience with adhesive techniques for creating strong joints
  • Familiarity with geometric shapes and their load-bearing capabilities
NEXT STEPS
  • Research effective adhesive types for wood bonding, such as PVA glue or epoxy
  • Explore structural design techniques, focusing on triangular bracing
  • Investigate load distribution methods in engineering
  • Learn about testing methods for structural integrity under weight
USEFUL FOR

This discussion is beneficial for students in engineering or architecture, hobbyists interested in structural design, and educators looking for practical applications of physics and material science principles.

Homework Statement


I was just wondering if anyone would like to give me an opinion on how best to build a popsicle stick "tower" that must be able to withstand 100 lbs, or preferably higher.

Perameters are as follows: I have been given 100 grams worth of sticks. The structure must be 15 cm wide, and 15 cm tall. My instructor will insert a 2 inch diameter pipe through the middle (must be 'hollow').

Homework Equations

The Attempt at a Solution



Im thinking of a square base with a four-cornered 'skeleton' extending upwards. On the sides of the tower I will form "triangles" with the sticks to help hold the weight.

Any opinions and all thoughts are appreciated.

Sounds good! Workmanship is important - you need strong glue joints. If you have extra sticks, use them to double the strength of the joints.
