1.The relative velocity of two infinitely wide parallel plates thatare 1cm apart is 10cm/s. If the dynamic viscosity of the liquid between the plates is 0.001 N s/m2 what is the shear stress between the plates?
2.Express each of the three forces acting on the bracket in Cartesian vector form with respect to the x and yaxes. Determine the magnitude and direction θ of F1 so that the resultant force is directed along the positive x'axis and has a magnitude of Fr = 600 N.
3.If φ = 45 degrees, F1 = 5kN, and the resultant force is 6kN dircted along the positive y axis, determine the required magnitude of F2 and its direction θ.
