To get F_fr in terms of T, R, and r, I substituted the moment of inertia and the expression for alpha into the net torque equation. Solving that for M*a, I then substituted into the net force equation and solved for F_fr, which, after some algebra, ends in the glorious result: ...
There is an alternative, but I even hate to mention it, because it perpetuates mindless business-calculus approach to physics problems: maybe there is a kinematical equation in your book/notes that deals specifically with a drag force that is proportional to velocity. If that is the case, it...
When is the frictional force equation valid? Does the frictional force coefficient depend on speed? Why does the normal force not cause any acceleration? Is frictional force positive or negative? Is tension a frictional force? How can you determine friction force?
The equation displays a rich spectrum of dynamical behaviors: periodic stick-slip, erratic, and intermittent motions, characterized by force fluctuations, and sliding above the critical velocity. Boundary lines separating different regimes of motion in a dynamical phase diagram are determined. The ...
Frictional interfaces are found in systems ranging from biological joints to earthquake faults. When and how these interfaces slide is a fundamental problem in geosciences and engineering1–20. It is believed that there exists a threshold shear force, ca
Molecular Physics and Chemical PhysicsBy treating the non-adiabatic coupling terms (NACTs) in a molecular system as equivalent to a frictional force, the classical equation of motion is solved for a test case of quasi-H 3 + along the C 2 v axis and axes parallel to it, and it is ...

Depending on the problem context, the drag coefficient can be calculated from equations 3.3, 3.4, 3.7 or 3.8 and then used with equation 3.1 to calculate the force on the particle as it moves through the fluid. (3.9)Force=CD2ρfv2Ac Show moreView chapter Chapter Physics of control surface ...
1c) and σ0 represents the total frictional force per unit contact area with the plates; we use σ0 as a fitting constant. At the curved tip, the menisci in the pores between the grains collectively generate an effective interfacial tension at the scale of several grains that acts to ...
for the aforesaid multi-bearing element application, this external control input can be a “force control” signal which when used in conjunction with the “μSB level control” signal provides for the possibility of control over both input parameters of the frictional sliding force equation (i.e...
