Centrifugal governors are preferred to the inertia type governor because an inertia governor is highly sensitive and more prone to hunting. In case of centrifugal governors, the balls are operated by the actual change of engine speed, while in case of inertia governors, it is by the rate of change of speed. Therefore, the response of inertia governors is faster than that of centrifugal types.

Explanation:
Governors are devices that are used to control the speed of an engine. There are two types of governors: centrifugal and inertia type governors. Centrifugal governors are preferred over the inertia type governors due to the following reasons:
1. Sensitivity: The inertia type governors are highly sensitive and more prone to hunting as they are based on the principle of inertia. They respond quickly to any change in engine speed, and this can lead to unstable operation. On the other hand, centrifugal governors are less sensitive and respond more slowly to changes in engine speed, making them more stable.
2. Controlling Force: Inertia governors have less controlling force compared to centrifugal governors. This is because the controlling force in inertia governors is provided by the spring force, which is relatively weak. Centrifugal governors, on the other hand, rely on centrifugal force, which is much stronger.
3. Balancing: The inertia type governors pose problems in the balancing of inertia forces. This is because the motion of the governor is dependent on the mass of the flywheel, which makes it difficult to balance. Centrifugal governors, on the other hand, are easier to balance as they rely on the centrifugal force.
4. Cost: Inertia type governors have high initial and maintenance costs due to their complex design and need for precise balancing. Centrifugal governors, on the other hand, are relatively simple and have lower initial and maintenance costs.
Conclusion:
Centrifugal governors are preferred over the inertia type governors due to their stability, strong controlling force, ease of balancing, and lower cost.
