400 mm diameter shaft is rotating at 200 r.p.m. in a bearing of length 120 mm. If the thickness of

[@shahbaazkhan2208]

In calculating tangential velocity why you didn't consider the value of thickness?

Sir, How to determine type of fluid if shear strain rate and Shear stress values are given in the question?

Thank you so much sir

[@aravindar9977]

Thanks ❤️💫

Sir , power = force × velocity hota hai phir aapne torque × angular velocity kyu put kiya. Aur angular velocity hi kyu , when we already have the value of relative velocity.

[@CivilMantraa]

Because power lost in shaft is due to Torque and angular velocity..
