The difference was surface roughness of PI composites which would result in different frictional coefficient and wear mechanisms.
The retentive force of a clasp also depends on the frictional coefficient between the abutment and the clasp that was reported to be approximately 0.2 in the presence of saliva.
However, the cohesion and frictional coefficient of concrete in construction joints are still insufficiently interpreted, particularly for high-strength concrete with smooth surfaces.
In this study, a friction test was conducted to identify the frictional coefficient between the quick-hardening track and bridge deck.
where cos [theta] = [square root of (1 - 2[[mu].sup.2.sub.f])/2(1- [[mu].sup.'2.sub.f])], [[mu].sub.f] is the frictional coefficient between particle and the drop weight, and [[mu].sup.'f] is the frictional coefficient between particles.
Friction on the walls of the solids flow surfaces, such as the hopper walls, varies with the solid additive as well as surface roughness and frictional coefficient. Additionally, there is particle-to-particle friction that can cause segregation.
6, b shows the frictional coefficient variation of NBR samples in different crude oil temperatures.
The major finding was that the manner in which each lab measured slip displacement contributed to the greatest variability in frictional coefficient results.
To calculate the amount of torque required for a given bolt load, multiply the major thread diameter (0.161" in this case) by the load and then by the frictional coefficient, which is a dimensionless parameter typically ranging between 0.12-0.20.
However, the interpretation of the frictional pressure drop term, the most prominent aspect, is significantly different in the interpretation of the two phase flow dryness fraction and the overall frictional coefficient. The frictional term pressure drop is analyzed in detail as follows.
The test results showed that when the axial rate of loading was increased, the frictional coefficient between the pipe and the soil reduced, and the weight of the pipe had no effect on the frictional coefficient within the range of variables studied.
