Hi All,(adsbygoogle = window.adsbygoogle || []).push({});

Since from childhood we are reading a formula Torque,T = F x r where f is the force and r isthe radius , I want to just know in this formula how to calculate force.

My Problem:-

I got Barrel Drum whoes O.D is 762mm or 30 inches and whoes ID is 742.3 or 29.5 inches . And the Barrel Drum weight after rolling the Hyd Hose is about 1700kg and there is one shaft going through the centre of the drum and the shafts sits on two bearings on each sides.

I want to calculate the Torque required to turn this Drum should I use the formula T= Fx r or should I use another formula T= I x Alpha where I is moment of Inertia and alpha is Angular acceleration . in the formula T = F x r I dont know the value of F, how to calcu;ate F(force ) .

Can anybody help me to suggest which formula is the best in this situation.

Thanks

With Regards

Sunny
