- 1Dry friction force is non-conservative because the work done by the force depends on ______.the path taken
- 2______ are approximately equal if either the pulley rotates at a constant speed or if the pulley inertia is negligible compared to the other inertias in the system.Tension forces
- 3When the mass, radius, or inertia of a pulley, the tension forces in the cable may be taken to be ______.the same on both sides of the pulley.
- 4What is the kinematic relation between a wheel and surface for pure rolling motion?v = Rω
- 5For pure rolling, a wheel will roll without slipping if the _____ is smaller than the static friction force μ_sN.tangential force f_t
- 6The assumption of negligible wheel mass implies that there is no _____ on the wheels.tangential force
- 7For general planar motion, two force equations describe translational motion, and a _______ equation is needed to describe the rotational motion.moment
- 8The net moment M_G is caused by the action of the external forces and any _____ applied to the body.couples
- 9Sometimes it is more convenient to use a point of known _____ rather than the mass center or a fixed point.acceleration
- 10______ is the same regardless of whether point O, G, or P is used.angular acceleration α
- 11The energy equivalence method can be used to model a system as if it were in pure translation or pure rotation, but only if the motions of the rotating and translating components are _____.directly coupled
