The recessional velocity of a galaxy at a particular distance inferred from Hubble's law is called the "Hubble velocity". ... If the primary is 2 units from the barycenter and the companion is 10 units from the barycenter, what is the lever ratio? 10/2 = 5. 1:5 is the ratio.

So using our formula (that we just memorized!)… Angular Velocity Notes p. 3 . 3. Jill’s Problems. The tractor, pulley, or . gear-ratio. problem. In these problems (unlike pts A & B), the omega’s (angular velocities) are not equal but the linear speeds are equal. Also in gear-ratio problems, linear speed is equal, . The . Gear-Ratio Theorem

velocity ratio, VR = wo/wi = w4/w1 = (-N1/N2)(-N2/N3)(-N3/N4) = (-N1/N4) (eq. 1) In this arrangement, the intermediate gears do not affect the overall velocity ratio, and therefore should be replaced with a more cost effective means of power transmission.

Therefore, torque can be talked about reference to it’s formula t = f * l (torque equals force times lever arm length {radius of gear}). It can also be looked at reference gear ratio too. Example: if a motor can lift 10 lbs, and it is geared to a second shaft that has a 2:1 ratio, it can by using this setup lift 20 lbs.

1. Slope 2. Drag Factor 3. Minimum Speed 4. Radius of a Curve 5. Critical Speed 6. Combined Speed 7. Velocity The coefficient of friction is the ratio of forces, expressed as the ratio of force needed to propel an object across a surface at constant speed (= force of friction) relative to the force exerted by the object onto the surface (its weight).

V is the average fluid velocity in the pipe in ft/sec (m/s for S.I) (The definition of average velocity is: V = Q/A, where Q = volumetric flow rate and A = cross-sectional area of flow) is the density of the fluid in slugs/ft3 (kg/m3 for S.I.) is the viscosity of the fluid in lb-sec/ft2 (N-s/m2 for S.I.)
