Answer:
The correct answer is True.
Explanation:
The feedback control system implies that to make a feedback, there must first be an error, otherwise there will be nothing to correct.
This system works so that there is an output that is controlled through a signal.
This signal will be feedback and it will signal an error which will be detected by a controller that will allow entry into the system.
In basic words, this system processes signals, samples them in the form of an output, and re-enters them feedback to detect the error signal.
Answer:
C. Provides lubrication to parts
Explanation:
Flywheel :
Flywheel is a device which stored the mechanical energy.This energy can be use when more energy required during any operation.Due to high moment of inertia of the flywheel it resist the change in the speed .The flywheel is attached to the crank shaft at the rear side of the engine.
The flywheel perform following function:
1. It connects the crankshaft and the transmission system.
2.It makes the engine operation smooth.
3.It contains gear and other parts of the engine.
But it can not provide lubrication.
C. Provides lubrication to parts
Answer:
vapor fraction = 0.4 and 0.08
Explanation:
At reasonably high temperatures, a mixture will exist in the form of a sub cooled liquid. Between these extremes, the mixture exists in a two phrase region where it is a vapor liquid equilibrium. From a vapor-liquid phase diagram, a mixture of 40% A, 39% B, and 21% C separates to give the vapor compositions of 0.4 and 0.08.
