Calculating Short Beam Strength of Liquid Nails

[DyslexicHobo]

I am trying to calculate the "short beam strength $$(\sigma_{sbs})$$" of Liquid Nails (a wood adhesive). I did a strength test of two square beams held together by the Liquid Nails and recorded the data. I also have data of a strength test of one of the wooden beams by itself.

How would I go about calculating the short beam strength of this polymer? I know there is a way to extract it from the data I have, but I'm unsure of what equations to use and how to arrive at the number.

Thanks.

To calculate the short beam strength of Liquid Nails, you will need to compare the strength of the two beams held together with the adhesive to the strength of the single beam. This can be done by calculating the ratio of the two strengths, which is referred to as the "bond strength ratio." The formula for this ratio is: Bond Strength Ratio = (Strength of Bonded Beam) / (Strength of Single Beam)By taking the ratio of the two strengths, you can determine the short beam strength of the polymer.
