Wind tunnels are used by engineers to test the aerodynamics of many objects, from jet wings to car windshields. Aerodynamics as a science studies the flow of air or gases around an object in motion. With a better understanding of the way air moves around (or through) objects, manufacturers...
S = 3Fl/2bh2 where F is the maximum load exerted on the specimens in Newton; l is the distance (20 mm) between the supports, with an accuracy of ±0.01 mm; b is the width (2 mm ± 0.01 mm) of the specimens measured before testing; ...
