Задача №17.11

Условие

Стержень AB скользит точкой A по горизонтальной прямой и промежуточной точкой C касается круга радиуса r. Определить уравнение неподвижной и подвижной центроид стержня.

Решение




Предыдущая задача №10
Найти приближенные уравнения неподвижной и подвижной центроид шатуна AB кривошипного механизма, предполагая, что длина шатуна AB=l настолько велика по сравнению с длиной кривошипа OA=r, что для угла ABO=α можно принять sinα=α и cosα=1; оси координат указаны на рисунке.
Следующая задача №12
Колесо катится по наклонной плоскости, образующей угол 30° с горизонтом (см. рисунок к задаче 16.2). Центр O колеса движется по закону xO=10t2 см, где x — ось, направленная параллельно наклонной плоскости. К центру O колеса подвешен стержень OA=36 см, качающийся вокруг горизонтальной оси O, перпендикулярной плоскости рисунка, по закону φ=(π/3)sin(πt/6) рад. Найти ускорение конца A стержня OA в момент времени t=1 с.
