Question

A fly wheel rotates at a constant speed of 3000 rpm(rev/min).
The angle described by the shaft in radian in one second is:
2017-Eng
A.2 pi
B.30 pi
C.100 pi
1.3000 pi​

Answer 1

Answer:

=100radians/sec

Explanation:

angular velocity= 3000 (in number of resolutions)

angular velocity=2πn

where n - number of revolutions/min

= 2π*3000

=6000π /min

=6000/60 for radians/sec

=100radians/sec
