A $25-$mm$-$diameter shaft is pulled through a cylindrical bearing as shown below. The lubricant that fills the $0\mathrm{.}3-$mm gap between the shaft and bearing is an oil having a kinematic viscosity of $8\mathrm{.}0\backslash$times $1042/$ and a specific gravity of $0\mathrm{.}91.$ Determine the shear stress and the total resistance force developed on the shaft surface when pulling the shaft at a velocity of $3$ m$/$s$.$ Assume the velocity distribution in the gap is linear $($
