Ive been trying to find formulas that help describe the torque needed to rotate a flat disk on a flat surface when the coefficient of friction between the 2 materials is known.
The first surface is a glass window (so a vertical plane) the second surface is a rotating disk of wet sponge "cleaing it" (also a vertical plane).
So I am looking for a formula that takes into consideration friction between the surfaces, speed of rotation, radius (or area) of the contact surface and torque required to start the disk spinning.
Any suggestions?
