Assertion (A): The supply of fuel is automatically regulated by governor according to the engine speed.
Reason (R): The automatic function is the application of d'Alembert's principle.
The correct answer is option 'C': A is true but R is false.
Explanation:
Governors are devices used in engines to control the speed of the engine by regulating the fuel supply. They are designed to maintain a constant speed of the engine, regardless of the load applied to it. The governor system is an integral part of most internal combustion engines, including diesel engines and gasoline engines.
Governors operate based on the principle of centrifugal force. They consist of a set of flyweights that are connected to the fuel supply mechanism. When the engine speed increases, the centrifugal force acting on the flyweights also increases. This causes the flyweights to move outwards, which in turn closes the fuel supply valve, reducing the fuel flow to the engine. On the other hand, when the engine speed decreases, the centrifugal force acting on the flyweights decreases, allowing them to move inwards. This opens the fuel supply valve, increasing the fuel flow to the engine.
The purpose of the governor is to ensure that the engine speed remains constant, regardless of the load variations. When the load on the engine increases, the speed tends to decrease. The governor senses this decrease in speed and increases the fuel supply to compensate for the increased load, maintaining a constant speed. Similarly, when the load on the engine decreases, the governor senses the increase in speed and decreases the fuel supply to maintain the desired speed.
Now, coming to the reason given in the question, it states that the automatic function of the governor is the application of d'Alembert's principle. However, this is not correct. d'Alembert's principle is a concept in classical mechanics that deals with the equilibrium and motion of particles and systems. It states that the sum of the applied forces and the inertial forces acting on a particle or a system is equal to zero. While d'Alembert's principle is certainly applicable in the analysis of systems like engines, it is not directly related to the automatic function of the governor.
Therefore, the correct answer is option 'C': A is true but R is false, as the supply of fuel is indeed automatically regulated by the governor according to the engine speed, but the reason given is incorrect.
Reason (R): The automatic function is the application of d'Alembert's principle.
The correct answer is option 'C': A is true but R is false.
