Задача id12619

Two loads with masses m1 and m2 (Fig. 18) lie on a smooth horizontal plane and are connected to each other by a thin thread that can withstand the greatest load P. Determine the maximum force F with which the load m1 can be pulled so that the thread does not break. Will the magnitude of this force change if m2 is pulled? Neglect the friction of the loads on the plane.
