Scarf joint

Some special angles should be noted or the graphs of two equations should be compared on the same plot. The joint is weakest at α=90 due to tension limits and 45 due to shear limits. However, α=45 will be stronger than α=90 if shear strength is greater than σ/2. The joint is strongest between these two angles at 63.4 . The joint becomes stronger than 63.4 at 25.4 . At a shallow .
