Jun 28, 2012 · this reasoning explains why figure 1, in which ω decreases by only 2.5 rad s −1, is accurately fit by equation.in conclusion, frictional torque terms proportional to both the first and zeroth powers of the angular speed are needed to accurately fit the deceleration of an undriven wheel rotating to rest (as evidenced by figures 2 and 3). The bearing will come into play and create frictional torque around the shaft, to do that you will have to know the frictional coefficient of the bearing.

Drill string friction coefficient can also be determined by measuring the torque while turning the drill string off the bottom. Note the additional torque required by the motor to over come some external/thrust force (greater than friction alone) during segment 2, and the lack of this required torque during the dwell segment 4.

Since calculated torque values are a function of the friction coefficients between mating threads and between the bolthead or nut and its mating surface, it is vitally important that the torque table values used are adjusted to reflect any differences in friction coefficients between those used to calculate the table and the user's values. When the total frictional moment, m, of the bearing is known, you can calculate the bearing frictional power loss using.

= 0,15 For N = 0 (Starting Torque Calculation)

5gsin30 = 5gcos30 × μ. For the equations to make sense, the mass value is limited to positive values only, the friction coefficient between [0, 2] and the pull force angle between [0°, 90°]. The net torque is equal to the angular.
