Building and Construction Science Fair Project

Testing the Strength of Arches

Medium
Testing the Strength of Arches | Science Fair Projects | STEM Projects
Ever wondered how strong arches can be? Test it out in this science project and find out how much weight an arch can hold before it breaks.

Hypothesis

The hypothesis is that a larger arch is able to withstand a heavier load.

Method & Materials

You will build an arch using plywood and bricks, hang a pail from it, and measure the weight of the load before the arch breaks.
You will need plywood, a pail, tap water, a weighing machine, two fixed pillars, a saw, a ruler, and bricks.

Results

The experiment showed that the strength of the arch peaks at a plywood length of 650mm. This proves that larger arches are able to withstand a heavier load.

Why do this project?

This science project is interesting because it shows how ancient structures like arches can still be used in modern construction.

Also Consider

Experiment variations include using different types of wood and varying the width of the plywood.
