Very large diesel engines are started using :
(ಗ) Compressed air (B) Electric starter motor
(0 Hydraulic starter motor (D) Hand eranking

The one way clutch (overrunning clutch) is used in starter motors [5 =
(A) Automatically engauge the starter pinion to flywheel
॥ To disconnect the engine from gearbox before starting
(C) Disengauge flywheel from starter pinion after starting
(D) Disengauge engine from propeller shaft

The Safeway to connect starter battery terminals on board ship is :
(A) conneet positive terminal first, then negative terminal
18) connect negative terminal first, then positive terminal
(€) connect positive and negative terminals simultaneously

(D) all are safe
The lead-acid battery rooms to be well ventilated to avoid fire hazards, because of :
(A) chances of acid leakage ए) emission of oxygen gas
(€) chances of spark (D) emission of hydrogen gas
Open circuit voltage of a single cell of lead acid battery is :
(A) 1.1volts (छ) 2.1 valts
(0) 12volts (D) 24 volts

Alternating voltage is generated by :
(ಗ) Ratating a coil in the magnetic field
(B) Rotating a magnetic field within a stationery coil
(C) Both A and B are correct
(D) Both A and B are wrong

The voltage generated in an alternator depends on :
(A) The number of term in the coil
(B) Strength of magnetic field
(C) The speed of rotation of the alternator
(D) All of the above

The purpose of capacitor of a single phase induction motor is :
(A) toincrease efficiency
(ಗ) for starting
(©) tocaol the motor
(12) to reduce the weight of the motor
