about torque
hi,
torque= ang.accleration x moment of innertia
(nm ) =deg/sec.sq x nm2
but from above conversion,how to reach to get nm
& also if we convert deg/sec.sq into rad/sec.sq,
value will be reduced by 57 times
my question how to get .....nm
thanx in before

find a job or post a job opening
your units are not correct.
the units for polar moment of inertia are: kg*m^2
the units for angular accel. are: rad/sec^2
radians are not a true engineering unit so they do not enter into cancelling out. that leaves you with:
(kg*m^2)/sec^2 = n*m
hi fredgravin
heartly thankful to you for giving this valuable
information
with warm regards

the radian is an engineering unit. degrees are not.
the radian measure of an angle is defined as the arclength divided by the radius of the arc. it is thus dimensionless, and hence disappears when dimensional analysis is performed to determine the resulting units of a formula.
take care.
