Задача №22.20
Условие
Механизм состоит из двух параллельных валов O и O1, кривошипа OA и кулисы O1B; конец A кривошипа OA скользит вдоль прорези в кулисе O1B; расстояние между осями валов OO1 равно a; длина кривошипа OA равна l, причем l>a. Вал O вращается с постоянной угловой скоростью ω. Найти:1) угловую скорость ω1 вала O1 и относительную скорость точки A по отношению к кулисе O1B, выразив их через переменную величину O1A=s;
2) наибольшие и наименьшие значения этих величин;
3) те положения кривошипа, при которых ω1=ω.
