Torque =moment of inertia*acceleration.
Therefore acceleration =torque/inertia.
=45/20=2.25 rad/square seconds.
If initial velocity is zero then final velocity=0+[15*2.25]=33.75 rads/second'
Now convert the rad/sec to rev/min
=33.75*60/2pi=322.3 rev/min.

(Solved)
A short circuit fault is located by varley loop test. The ratio arms are set at P=5 ohms and Q=10 ohms and the values of variable resistance S are 16 ohm for position 1 of switch K and 7 ohms for position 2.The sound and the faulty cables are identical and have a resistance of 0.4 ohms/Km. Determine the length of each cable and the distance of fault from the test end.
