Thread: Help with a technical question in mechanical engineering (a little challenge,maybe?:)

It seems to be true, yet the first case doesn’t correspond to the description.
It says, “The screws are in equal radius from each other”.
Screws could be at a radius distance from each other if only there were six of them. There are only four of them here.

Ahh my bad Helen-- it was supposed to be "by 12 screws with equal radius distribution" (not "with equal radius from each other" like I originally and stupidly wrote).


Anyway, I think this thread got a bit derailed...I'll write the English version of this question-- if anyone can please help me translate it to Russian I'd appreciate it:

The flange connector shown in the drawing is fastened by 12 screws at equal radius distribution (R=125mm). On the connector acts an external bending moment M=10 kNm

Calculate:
1) The force acting on the screw with the most load.
2) Pick an appropriate bolt

Given:

Allowable strain at screws = 100 MPa
The friction coefficient for the thread is 0.12

Фланцевое соединение, показанное на рисунке, закреплено 12 винтами, равномерно распределенными по окружности радиуса R=125 мм. На соединение действует внешний изгибающий момент М=10 кНм.

Рассчитать:
1) Силу, действующую на винт с наибольшей нагрузкой.
2) Подобрать подходящий винт.

Дано:

Допустимое напряжение на винтах = 100 МПа.
Коэффициент трения в резьбе 0,12.
