Anewtonian, incompressible fluid fills a gap of height, h, between two flat plates. the plates are of width, w and length, l. the top plate moves to the right with a velocity of v. what is the force required to move the plate at this velocity? assume the process occurs at steady state. repeat the problem for a bingham plastic to determine the minimum velocity, v, as a function of other parameters required for flovw between the plates. also, calculate the force at this velocity. assume the flat plates are your teeth and a tooth brush, respectively, and that tooth paste acts like a bingham plastic. if the yield stress for toothpaste of 100 pa with a viscosity of 100 cp, calculate the minimum velocity and force at this velocity. make reasonable assumptions for h, w, l.]

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
