53 2-Ar Question 3 (7 points) A motor is used to accelerate the two block and pulley system. It is connected to the pulley through a gear box of ratio 1:6. The two blocks acceleration is 2 cm/s.. Calculate the motor torque Ty knowing that: 1. The friction torque Tr is one tenth (1/10) of the acceleration torque T 2. The pulley and blocks masses are such as m = ma mp/5=1 kg. 3. The pulley radius is rp = 30 cm. 4. The mass moment of inertia of the motor is double the mass Tu-? moment of inertia of the pulley Iy 21p. Note that Ip mptp/2. 252cm/52 T+=+ To 0.5 Ta A B Wp- Wyn
