Question:
An experiment is performed with a pin-on-disk tester to evaluate the shear strength of a lubricant. The
experiment involves sliding of a spherical pin of hard steel against a copper plate of hardness equal to 120
kgf/mm2 . Both specimens are immersed into a bath of the lubricant and slide under a low speed (boundary
lubrication regime). The radius of the pin is 2 mm and the width of the wear track produced from sliding is
0.5 mm. Strain gages attached to a cantilever beam supporting the pin indicate that the total coefficient of
friction is 0.2.
Determine (a) the shear strength of the lubricant and (b) the reduction of the work of adhesion in the
presence of the lubricant. Clearly state any assumptions you make.
