Assume we braze two thin-walled high-strength low-alloy steel tubes together with a sleeve joint. calculate the overlap length that is needed to ensure that the joint is stronger than the tubes. for the joint’s shear strength, a value of 20 mpa is typical. (10 points) hint: in this comparison you will find that the tube diameter drops out of the equation. you will still need to assume a certain tube wall thickness though, and you will also need an assumption for the tensile strength of low alloy steel (which you can get from any good materials database).
