Question 1
A system of two gears with moments of inertia 3 kgm² and 4 kgm² respectively is connected. If the smaller gear spins at 5 rad/s, what will be the angular velocity of the larger gear?
💡 Hint: Remember to apply the principle of conservation of angular momentum.
Question 2
Design a gear mechanism that can effectively transmit torque from a motor to a wheel with specific gear ratios. Explain your rationale for the selected ratios.
💡 Hint: Consider how the gear ratio influences speed and torque in the system.
