Assertion (A): Relative stability of the system reduces due to the presence of transportation lag. Reason (R): Transportation lag can be conveniently handled by Bode plot.

Correct Answer: Both A and R are true but R is correct explanation of A
Transportation lag can be conveniently handled on Bode plot as well without the need to make any approximation.

Determine the corrections or otherwise of the following Assertion and Reason : Assertion : For longitudinal static stability of an aircraft, slope of moment curve should be negative. Reason: Positive slope will result in more static stability than negative slope. Hence, slope should be positive always. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Direction-The question have two statements.
One is labelled as Assertion (A) and the other as Reason (R). You have to examine both the statements carefully and decide whether Assertion (A) and Reason (R) separately are true and if so then reason is the correct explanation of the assertion. Mark these items on the answer sheet.
Assertion (A): Interest payable on working capital should be treated as an item of operating expenses.
Reason (R): Interest is the cost of capital used in the business.

The question contains two statement. One is Assertion (A) and the other is Reason (R). You have to examine both the statements carefully and decide whether the Assertion (A) and Reason (R) are separately true? and If so, then Reason is the correct explanation of the Assertion. Mark these items in the balance sheet.
Assertion (A) Balance sheet does not reveal ownership of business.
Reason (R) Assets are just unrefined cost.

Assertion (A): The phase angle plot in Bode diagram is not affected by the variation in the gain of the system. Reason(R): The variation in the gain of the system has no effect on the phase margin of the system.

A big rectangular plot of area 4320 m2 is divided into 3 square-shaped smaller plots by fencing parallel to the smaller side of the plot. However some area of land was still left as a square could not be formed. So, 3 more square-shaped plots were formed by fencing parallel to the longer side of the original plot such that no area of the plot was left surplus. What are the dimensions of the original plot ?

Consider the following statements with respect to the feedback of the control systems. i. Feedback can improve stability or be harmful to stability if it is not properly applied. ii. Feedback can always improve stability iii. In many situations the feedback can reduce the effect of noise and disturbance on system performance. iv. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

Consider the following statements with respect to the feedback of the control systems: 1. Feedback can improve stability or be harmful to stability if it is not properly applied. 2. Feedback can always improve stability 3. In many situations the feedback can reduce the effect of noise and disturbance on system performance. 4. In general the sensitivity of the system gain of a feedback system of a parameter variation depends on where the parameter is located.

According to Bode stability criterian, a system is unstable, if the open loop frequency response exhibits an amplitude ratio exceeding unity at frequency for which phase lag is

Direction: The following question consists of two statements.
One is labeled as Assertion (A) and the other as Reason (R). You have to examine both the statements carefully and decide whether Assertion (A) and Reason (R) separately are true and if so, the reasoning statement is the correct explanation. Mark these items on the answer sheet.
Assertion (A): Social responsibility of business is an idea which cannot be put into action in most of the professions.
Reason (R): There are no standards by which the extent of responsibility of each segment of the society can be measured.

Assertion (A): The closed loop stability can be determined from the poles of an open loop system and the polar plot of the frequency response. Reason (R): Unstable system has right half poles.
