I think i might know the answer. It is the applicable for both cases but only at the root of the thread, since both are rectangles. One side of the ACME thread root shape (rectangle) it is slightly higher than 1/2 P but .... I believe it can be applied for both cases either way.
@@axeld9108 I can't talk for acme (I'm UK but assume it will be the same) - for a metric trapezoidal thread the height of the trapezoid is equal to p/2 at the mean diameter (dm) at 1/2 the distance between the minor and major diameter, which is where you assume the critical stress location and a point source F. This then makes p/2 valid and why it can be used for both. One side of the trapezoid is higher than p/2 and the other is smaller than p/2.
Hi, the video was great, but i would like to know how do we verify the strength after we have calculated the Von mises.
Hi, great lecture! I just have a question.... The bending stress equation used is applicable for square and ACME profile? Thank you in advance.

You got it right! Yup
