1 1.63. The following parameters of the arrangement of Fig. 1.11 are available: the angle a which the inclined plane forms with the horizontal, and the coefficient of friction k between the body m₁ and the inclined plane. The masses of the pulley and the threads, as well as the friction in the pulley, are negligible. Assuming both bodies to be motionless at the initial moment, find the mass ratio malm, at which the body m, (a) starts coming down; (b) starts going up; (c) is at rest.
