Your videos are amazing. Thank you. There is a question for the ka table. Values are different than most of the other tables why?

Can u explain how u found point of loading P = 500, 300mm from the left? did u assume the assembly was loaded in its center?

@reylandregis2791 3 ай бұрын

How do you acquire notch sensitivity factor (q) not using the charts? In my design, I have notches with radius 5, and 7.2 mm which are both out of scope of the chart.

Formula for Kt is wrong

@LessBoringLectures 3 жыл бұрын

Can you point to the time in which this happens? I already checked the entire video, and I found nothing wrong with the Kt expressions.

You showed the wrong formula for kf, it's upside down, by your formula kf will be between 0-1

@@LessBoringLectures check on 1:01 in time! That one (Notched/ Notch-free) should be correct! Make it upside down!

@jamesthecoolguy7615 2 жыл бұрын

@@neutroviolet2918 How though? Surely if there is a notch then the fatigue life will be less than the notch-free fatigue life, so the Kf value has to be greater than 1
