...Peter C. Chu; Chenwu Fan; Paul R. Gefken Prediction of a rigid body falling through water column with a high speed (such as Mk-84 bomb) needs formulas for drag/lift and torque coefficients, which depend on various physical processes such as free surface penetration and bubbles. A semi-empirical...

... thank Prof. Dane Quinn of the University of Akron for introducing them into the world of the Padé approximation. The above analysis illuminates several points. 1 The Deresiewicz approximations for torque and for dissipation are best used only in regimes of very small rotation. 2...

...G. Cheng; J. W. Zu, Associate Professor In this paper, the rotational vibration of a belt drive system with a dry friction tensioner subjected to multiple harmonic excitations is studied. The work is focused on the impact of the dry friction torque combined with the multiexcitation frequencies...

... strength β related to a torque imposed by wind drag. This stem torque can cause nonlinear coupling if both X I and X II are excited and if k I ≠ k II , such that damping can vary by 30 percent over each cycle. The directionality of the single stalk may promote interplant collision, which could have...

... for fibers and films on rollers undergoing cold draw. We apply our equations to the problem of torque transmission by a belt between two pulleys, and compare the resulting solution to solutions in which centrifugal acceleration is included but stretching acceleration is neglected (the common engineering...
