The main difference between an open loop system and closed l

The main difference between an open loop system and closed loop system is that the feedback goes to the starting point in an open loop system. In gyroscopic motion, precession occurs when the axis of the rotor is turned whilst the rotor rotates about its axis. Laplace transforms simplify expressions to simpler ones that can be more easily solved. Select from the expressions below the one that best describes statements (A) to (C) (1) Expression (B) only is correct. Expressions (A) and (C) only are correct. Expression (C) only is correct. Expression (A) only is correct. Expressions (B) and (C) only are correct.

Solution

Statement 1 is incorrect because in open feed back system, the feed back would not return to the starting point. since it doesnot form a complete

Statement 2 is correct precission occurs when the axis of the rotor is turned whilst the the rotor rotates about its axis

Statement 3 is correct laplace operation transforms the high complex function in one variable to a simple form of function in another variable

from analysis of the above statements it is found that option E is correct choice
