Solution of the D2 B27. To accelerate the rotation of the turbine to the torque applied thereto which depends on the angular velocity of the turbine and time: M = 1,2t / w2. The initial angular velocity of the turbine w0 = 4 rad / s. The moment of inertia about the axis of rotation of the turbine is equal to J = 0.2 kgm2. To determine the angular velocity of the turbine 2 seconds after the moment of application.

Right after the payment you receive a link to the archive with the solution of the problem in theoretical mechanics A2 B27 (condition 27) 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.
