Experimenting for Project

The first test the team has done was to check the structural rigidity of the ply vs pine, the results are listed below.

Aim:

Testing to see which has more strength against weight. Pine or ply.

Method:

We are going to make a plank of pine and ply that have the dimensions of 50 x 20 x 1000 (mm) for fair testing. We will introduce unifrom weight force which we allow us to see the resistance added against the weight.

Controlled variables:

The mass of the weight we are putting on each plank of wood.

The orientation of the plank where the weight is applied (which will remain length ways/vertical)

Variables:

We will be changing the different materials of the plank. So a uniform plank of pine and ply will be used in this experiment

Conclusion:

We concluded that the pine gave the better result as the pine has more fiber and grain going in the same direction than the ply wood. The reason is that the ply has a 90 degree rotation in the layers so only half of the 18mm ply will have the grain leading in the same direction as the pine. However we discovered that the ply would be used the best if it was used for external panelling like the sides as it is easily moulded in the various shapes we require for our project.

This video shows the results of this the first experiment that the team has done in the design phase.
