When the coil is powered, a magnetic field is generated around the armature. The left side of the armature is pushed away from the left magnet and drawn towards the right, causing rotation. When the coil turns through 90 0 , the brushes lose contact with the commutator and the current stops flow..

The table shows the details of motor vehicle registrations for the year 1995, 1999 and 2000. Use the table to find the ratio of the motor vehicle registrations in the year 1995 to that in the year 2000. => 1 : 5 or 1 : 2 or 8 : 9 or 4 : 3..

In a state where the use of helmet is mandatory for all riders, 154 out of 160 motor cyclists randomly observed were found to be using helmets. Test the hypothesis at α = 0.01 that less than 98% of the motor cyclists use this safety gear. => z = - 1.58, reject the hypothes..

A motor cycle wheel is designed with the rim diameter of 16 inches and tyre radius of 8.3 inches. Find the allowance for the air gap between the rim and the tyre. => 7.7 inches or 3.85 inches or 0.3 inches or 0.4 inches..
