Задача id12171

For a system of bodies connected by weightless and inextensible threads, determine the steady tension of the thread between bodies m1 and m2, provided that the initial speed of the bodies is zero. Masses of bodies m1=1 kg; m2=2 kg; m3=3 kg; the angle of inclination of the planes to the horizon line is a=45°; coefficient of friction between body m1 and inclined plane u=0.3; bodies m2 and m3 do not experience frictional forces; there is no friction in the block.
