A drive shaft has a speed 150pi radians a second. What is the speed in RPM?
- 4500.
- 9000.
- 1500.
Explanation from PART66Online
To convert from rad/s to RPM, multiply by 60 / (2 pi). So 150 pi x 60 / (2 pi) = 150 x 30 = 4500 RPM. Each revolution is 2 pi radians, and there are 60 seconds in a minute.

150×60÷2=4500 rpm
Here 150Î =150 half revolution= 75 revolutions
For complete revolution this will be equal to
