# What is Dimensional Formula of Torque?

Posted in Dimensional Formulae | Email This Post |Force causes accelerations and Torque causes angular accelerations.Torque is proportional to the distance between the rotation axis and the point of application of the force (the point at which the force is applied).

Mathematically, Torque is defined as product of Angular acceleration and Moment of Inertia. Its formula is

**Torque = Angular Acceleration X Moment of Inertia**

Dimensional Formula of Angular Acceleration = M^{0}L^{0}T^{-2}

Dimensional Formula of Moment of Inertia= M^{1}L^{2}T^{0}

Putting these values in above equation we get

**Dimensional Formula of Torque= M ^{1}L^{2}T^{-2}**

SI unit of Torque is N m

I like dis site

torque is nothing but a force but in rotating system

the force causes acceleration but torque causes angular acceleration

good site it is easy to know from this

thank you.

throgh this i got the formula of torque

I like dis site, Very useful

this is very helpful.

very informative site…..hav added it to FAVOURITES!! <3

Good

It’s very usefull

love this site

Thanks

I like dis site

I like this site

What are the primary dimensions of (v.gradiant)v where v is velocity

Its good …

explain in most simple way

Thank you
