A conceptually new textbook

- -.

Abstract

В начале 2013 г. в издательстве «Инфра-М» выходит из печати второе издание учебника «Тракторы и автомобили», принципиальное отличие которого от аналогичных состоит в том, что в нем наряду с теорией трактора впервые изложены методы оценки его технологических и тягово-динамических свойств. Ранее эти методы в вузах не изучались. Благодаря новым разделам предлагаемый учебник станет первым максимально приближенным к эксплуатационному направлению, по которому с.-х. вузы готовят специалистов инженерного профиля.
