Question details

A block that is a m square slides from left to right across a flat plate on a thin film of ol. The oil has viscosity μ Ns m2 and the film is h m thick. The block of mass M kg moves at steady speed u m s under the influence of constant force FN. (a) Find the magnitude of the shear stresses on the bottom of the block. Indicate the direction of the shear stresses on the bottom of (th block and (c) the plate. (d) If the force is removed suddenly and the block begins to slow, obtain an expression for the time required for the block to lose 88 percent of its initial speed. Round your numeric answer to 3 significant digits. (a) Tyx (b) Uto left (c) to right =-10.12 In
