Задача №23.3

Условие

Определить абсолютное ускорение какой-нибудь точки M спарника AB, соединяющего кривошипы осей O и O1, если экипаж движется по прямолинейному участку пути равномерно со скоростью v0=10 м/с. Радиусы колес R=1 м, радиусы кривошипов r=0,75 м. (См. рисунок к задаче 22.18.)

Решение





Предыдущая задача №2
Велосипедист на некотором участке горизонтального прямолинейного пути движется по закону s=0,1t2 (s — в метрах, t — в секундах). Дано: R=0,35 м, l=0,18 м, z1=18 зубцов, z2=48 зубцов. Определить абсолютное ускорение осей M и N велосипедных педалей (предполагая, что колеса катятся без скольжения) при t=10 с, если в этот момент кривошип MN расположен вертикально.
Следующая задача №4
Найти скорости и ускорения точек M1, M2, M3 и M4 гусеницы трактора, движущегося без скольжения по прямолинейному участку пути со скоростью v0 и ускорением w0; радиусы колес трактора равны R; скольжением гусеницы по ободу колес пренебречь.
