Solution of the D2 B30. Pulley (uniform ring) weighing 200 kg and a radius of 40 cm is rotated from standstill torque M1 = 80 Nm, testing the resistance force, the moment where M2 = 1,2w2. Determine at what angle turn the pulley until it becomes equal to the angular velocity of 4 rad / s.

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics D2 B30 (condition 30) in the test book "theoretical mechanics" Dievskaya VA Malyshev IA 2009 for university students.
The decision is decorated in a format word (typed or hand-written decision in a Word), packed to the archive zip (open on any PC).

After checking the solutions I would be very grateful if you leave your positive feedback.
