Carbonara X Beam Prototype Testing 2
I've rerun some tests on a prototype of the Carbonara X beam, to actually measure numbers to be able to more objectively compare the performance at different temperatures.
I loaded the beam with a clamp pulled off axis with a load cell and recorded the angles with my phone. A force of 6kg was used, always applied at the same point of the clamp (around 17cm off center). The 20cm sample was put in the oven for 10 hours at 100°C, and then 2 hours at 110°C.
Here are the average angular displacements measured:
- Ambient: +2.4°
- 100°: +2.4°
- 110°: +2.6°
Considering the standard deviations and inaccuracies, these are really good results. For both 100°C and 110°C I raised the temperature 3-4°C the last minutes to compensate for the cooling during the set up time on the table outside the oven.
The angles were measured considering the vertical sides of the tube, and not the horizontal ones, as the clamps were slightly deforming those ones in all the tests as I tightened the clamps as much as possible. This test, together with the previous ones, makes me confident the tube will fare well in 90°C chambers, maybe even slightly higher.
