    Friction Torque on a Rotating Disc

    sorry A = pi*r^2, so still using r^3/3 and substituting back in would still only give you 1/3*F*R*mu.

    Friction Torque on a Rotating Disc

    thread404-264188 On the thread listed above I was looking at it and had a question on how the final formula (T=mu*F*R*2/3) was formulated. when i take the double integral of r*dr*dthetha with the bounds of 0 to R and 0 to pi I get pi*R^2/2. I take P = F/A and A = pi*R^2/4 so substituting I...

    Axial and Radial Loads On Sleeve Retaining Blocks

    I have a sleeve with a varying OD 5.25" - 6", the ID is 5". The sleeve is retained on the shaft with 2 (2" x 1.5" x 2") retaining blocks. The sleeve is subject to 18,000 ft-lbs of torque. I need help in calculating the radial and axial loads on the retaining blocks from the torque on the sleeve...
