For phone system connected by weightless and inextensible threads, determine the steady tension of the thread between bodies m2 and m3, provided that the initial speed of the bodies was equal to zero. Body masses m1=1 kg; m2=2 kg; m3=3 kg; the angle of inclination of the plane on which the body m3 is located to the horizon line a=60°; coefficient of friction between body t2 and the corresponding horizontal surface u=0.2; bodies m1 and m3 do not experience frictional forces; there is no friction in the blocks.
