В одной из опор рамы возможно проскальзывание. Другая опора - стержень. На раму действуют две силы F и P и момент. Сила P задана. При каких значениях силы F возможно равновесие? Коэффициент трения известен. Составляем три уравнения равновесия и решаем одно простое неравенство.

One of the hings of the frame may slip. Other support - rod. Two forces F, P and moment are attached to the frame. The force P is given. For what values ​​of force F equilibrium is possible? The coefficient of friction is known. To solve the problem we need to write three equilibrium equations and solve a simple inequality.
