The x component of velocity in an incompressible flow field is given by u = Ax, where A = 2 s-1 and the coordinates are measured
in meters. The pressure at point (x, y) = (0, 0) is p0 = 190 kPa (gage). The density is rho = 1.50 kg/m3 and the z axis is vertical. (a) Evaluate the simplest possible y component of velocity. (b) Calculate the fluid acceleration and (c) determine the pressure gradient at point (x, y) = (2, 1). (d) Find the pressure distribution along the positive x axis.

Answer:
Because with this test you can determine complex material parameters like Young’s modulus, yield strength, ultimate strength and elongation at break. This is important because it provides us with the factor of safety that needs to be built-in the products using these materials.
Explanation:
This test consists in place the material between to tweezers to subdued the material into a stress-strain test. The figure shows the procedure.
In the x axe the strain and the y axe the stress.
