Assertion (A): DC servomotors are more commonly used in armature controlled mode than field controlled mode. Reason (R): Armature controlled Dc motors have higher starting torque than fiels controlled motors.

Correct Answer: Both A and R are true and R is the correct explanation of A
To get higher speed in field controlled dc motor, field current is decreased with decrease in torque.

Assertion (A): DC servomotors have practically taken over from AC servomotors in most control application. Reason (R): Low brush commutator friction and still higher torque/inertia have been achieved in DC servomotors.

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): Servomotors have heavier rotors and lower R/X ratio as compared to ordinary motors of similar ratings. Reason (R): Servomotor should have smaller electrical and mechanical time constants for faster response.

Determine the corrections or otherwise of the following assertion and reason : Assertion : Flying boats have higher values of empty weight fraction than that of the military aircraft. Reason: Military aircraft has to be lighter in weight. 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

Assertion (A): Slotted armature type in this armature is placed in slotted armature with DC windings placed inside the slots. Reason (R): The construction is highly reliable and rugged but has high torque.

Determine the corrections or otherwise of the following assertion and reason : Assertion : In general, wing twist should not be more than 6°. Reason: Wing twist is used to improve stall properties at tip. 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

Determine the corrections or otherwise of the following assertion and reason : Assertion : Fuel consumption is more for low level, high speed flight mission. Reason: At low altitude, the aerodynamic efficiency decreases drastically which affects the engine efficiency and range as well. To maintain cruise flight more fuel consumption is required. 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

Determine the corrections or otherwise of the following assertion and reason : Assertion : Aerobatic prop aircraft has much higher power loading. Reason: Power loading of prop aircraft is ratio of power to the weight of the aircraft. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) Both and are false d) is false but is true

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
