FRICTION, WEAR, AND ADHESION CHARACTERISTICS OF TITANIUM-ALUMINUM ALLOYS IN VACUUM by Donald H. Buckley and Robert L. Johnson Lewis Research Center SUMMARY Friction, wear, and adhesion measurements were made in vacuum (lo-' mm Hg) of titanium-aluminum alloys containing 11, 16, and 21 weight ...
Friction Abstract Students learn the principles of friction by demonstrating the effect of weight, angle and gravity on the speed of movement of objects.
Friction I. Theory Friction is the resisting force encountered when one surface slides over another; this force acts along the tangent to the surfaces in contact.
