Chapter 3, Problem 3.15P

Consider the spur gears shown in Figure P3.15, where $I_1=0.3\text{ kg}\cdot {\text{m}}^2$ and $I_2=0.5\text{ kg}\cdot {\text{m}}^2$ . Shaft 1 rotates three times faster than shaft 2. The torques are given as $T_1=0.5\text{N}\cdot \text{m}$ and $T_2=-0.3\text{N}\cdot \text{m}$ . Compute the equivalent inertia on shaft 2, and find the angular acceleration ${\stackrel{\dot{}}{\omega }}_2$ .
