8. Calculate and plot the change in the magnitude of the ultimate shear stress depending on the concentration of the red lead suspension in paraxylene. When using the method of tangential displacement of the plate, the following data were obtained:
Dispersed phase concentration, % 15 20 22 24 27
Maximum force Fm *102, N 0.28 1.26 2.1 2.38 2.94
The plate is 7 mm long and 5 mm wide.
