In the design test, a light sawtooth belt is wound around a sprocket (sawtooth wheel) with an average radius of r = 20 cm. The belt is horizontal and angular a = 15°, and both ends are fixed to the right vertical wall. Initially, the tension of the upper and lower belts is equal to T0 = 100 N. Find the tension T1 and T2 acting on the upper and lower belts when applying counterclockwise moment M = 10 N*m to the sprockets, respectively.
