A 10-kg block slides down a smooth inclined surface as shown in below figure . Determine the terminal velocity of the block if the 0.1-mm gap between the block and the surface contains SAE 30W oil at 60

For each of the three floating bodies, determine the buoyant force exerted by the liquid. Each body has a draft (depth of submergence) of 1.5 m. SG liquid = 0.8. 2 m (a) Body A 2 m 2 m ELEVATION VIEW 2 m OF 2 m (b) Body B PLAN VIEW 2 m OF 2 m (c) Body C For the floating bodies (a) Which has the greatest amount of buoyant force? (b) Which has the least amount of buoyant force?

Find the force required to pull a shaft with diameter D, steadily into a sleeve with diameter D, and length L at a velocity of V. The clearance between the shaft and the sleeve is filled with an oil of viscosity μ.

A torque is applied to rotate a cylindrical shaft (diameter D 1 , length L) at a constant angularspeed ω, inside a co-axial, stationary cylinder of the same length and diameter D 2. The gapbetween the bottom surface of the shaft and that of the stationary cylinder is h.(a) Develop a general expression of the torque in terms of the geometric dimensions andthe viscosity μ of an oil filling the gaps between the shaft and the stationary cylinder.Assume linear velocity profiles in all the gaps.(b) Determine the numerical value of the torque in the case of an oil of viscosity of 0.1Pa.s.
