Are you done with the paper yet, dear? (Senior Division).

The purpose of this project is to design and construct a durable, effective beam which can be used for construction. This type of beam will be made from recycled materials such as newspaper. I hypothesized that I can design and construct a beam equivalent in strength and purpose to conventional materials. This will reduce cost and the need for virgin woods. Blend shredded newspaper with water. Combine cornstarch and water and cook to form a binding medium. Combine newspaper and binding medium in a blender. Squeeze mixture. Press into molds. Place molds into the oven and cook until dry. Test the beams for strength using a three point bending test and a four point bending test. Test using a torsion, cantilever, shear, and compression test. I conclude that I was able to successfully design and construct a beam made from recycled newspaper which is equivalent in strength to virgin woods. After completing these test, I then compared the data to virgin woods. The beams modulus of elasticity compared to Oak and Douglas Fir which proved my hypothesis correct.
