Maximum Axial Load for OBLIQUE PLANE Stresses in 1 Minute!

Summary

This educational video explores the concept of shearing stress and strain through a practical example of a simple scarf splice in wooden members. It demonstrates how to calculate the maximum safe load, which is 1500 pounds, given a maximum allowable tensile stress of 75 psi. The video also computes the corresponding shearing stress to be 43.3 psi. Viewers are encouraged to check out additional resources for more examples on the topic.
